Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
In one aspect of the invention, a method of making an electrochromic device is presented. As mentioned above, the existing electronic device housing has a single color, and is difficult to meet the user's requirements. Specifically, the color of the existing electronic device housing is usually formed by a printing process or an oxidation process, and after the housing is manufactured, the color of the housing is fixed and cannot be changed. In addition, although the color of the existing electrochromic shell can be changed, the existing electrochromic shell can only present one color under a certain voltage and cannot simultaneously present multiple colors, so that the existing electrochromic shell has a single color and cannot meet the requirements of users.
According to the embodiment of the invention, the electrochromic layer in the electrochromic device is improved, specifically, a plurality of electrochromic materials are selected to form the electrochromic layer, after a certain voltage is applied to the electrochromic device, the plurality of electrochromic materials can present colors under the voltage, so that the electrochromic device can present a plurality of colors at the same time, and when the applied external voltage changes, the colors of the plurality of electrochromic materials also change according to the change of the voltage, thereby further enriching the appearance effect of the shell applying the electrochromic device. According to the embodiment of the invention, in the process of preparing the electrochromic layer, through the improvement of the preparation process, specifically, glue is arranged among a plurality of electrochromic materials, and the curing degree of the glue is controlled, so that the glue and the cover plate covering the electrochromic area have good adhesion, the cover plate is convenient to remove from the glue, the two adjacent electrochromic materials are not interfered with each other, and a plurality of electrochromic color blocks separated by a glue wall are formed finally, so that the electrochromic device can simultaneously present a plurality of colors, has bright colors and does not generate color mixing. The term "non-interfering" means that two adjacent electrochromic materials do not permeate or dope each other, and the boundaries between a plurality of electrochromic color blocks do not have obvious and macroscopic color mixing phenomenon.
According to an embodiment of the invention, with reference to fig. 1, the method comprises:
s100: a first electrode layer and an electrochromic layer are sequentially arranged on the first substrate, and the electrochromic layer comprises a plurality of electrochromic blocks
According to an embodiment of the present invention, in this step, a first electrode layer and an electrochromic layer are sequentially provided on a first substrate. According to an embodiment of the present invention, a first substrate is first provided, and the first substrate may be formed of glass or plastic. Thereby, the color of the electrochromic device can be transmitted out of the first substrate. According to an embodiment of the present invention, when the first substrate is formed of plastic, it may be formed of polyethylene terephthalate or polycarbonate. Thus, the cost of the electrochromic device can be reduced, and the electrochromic device can be patterned into a specific shape. For example, a circle, triangle, heart, etc., or may be a LOGO (LOGO), etc.
According to an embodiment of the present invention, a first electrode layer is then formed on the first substrate by sputtering. Specifically, when the first substrate is formed of glass, the first electrode layer may be formed by high-temperature sputtering, and when the first substrate is formed of plastic, the first electrode layer may be formed by low-temperature sputtering. Thus, the first electrode layer can be formed on the first substrate by a simple method. The specific temperature for sputtering is not particularly limited, and may be designed according to the applicable temperature of the specific material constituting the first electrode layer.
According to an embodiment of the present invention, at least one of the first electrode layer and the second electrode layer prepared in the subsequent step is formed of a transparent material. Specifically, the first electrode layer may be formed of a transparent material, for example, at least one of indium tin oxide and nano silver, and the second electrode layer may be formed of a non-transparent material, for example, a metal material, in which case the color of the electrochromic device may be transmitted from the first electrode layer and the first substrate side. Alternatively, the first electrode layer is formed of a metal material, the second electrode layer is formed of a transparent material, and the color of the electrochromic device can be transmitted from the second electrode layer to the second substrate side. According to the embodiment of the invention, the electrode layer formed by the metal material can also shield elements in the electronic equipment, and meanwhile, the metal material has a certain metal color, so that the electrochromic device can present a certain metal color when no voltage is applied to the electrochromic device, and the appearance of the electronic equipment is further improved.
According to other embodiments of the present invention, the first electrode layer and the second electrode layer are both formed of a transparent material, and the color of the electrochromic device can be transmitted from the first electrode layer, the first substrate side and the second electrode layer, the second substrate side, thereby facilitating the assembly of the electrochromic device and the housing substrate, without distinguishing the front side and the back side, and further simplifying the manufacturing process of the housing.
According to the embodiment of the invention, an electrochromic layer is formed on the side, away from the first substrate, of the first electrode layer, the electrochromic layer comprises a plurality of electrochromic blocks, the electrochromic colors of the electrochromic blocks are not identical, and two adjacent electrochromic blocks are separated by the glue wall. Thus, an electrochromic layer which can simultaneously express a plurality of colors and has a clear color can be formed. Specifically, referring to fig. 2, a
According to an embodiment of the present invention, the electrochromic layer may be formed by coating. Specifically, the electrochromic layer may be formed by screen printing, dip coating, curtain coating, roll coating, blade coating, or spin coating. Therefore, the electrochromic layer can be formed by a simple process and has high production efficiency.
According to an embodiment of the present invention, the electrochromic layer includes a plurality of electrochromic blocks, and referring to fig. 3, the plurality of electrochromic blocks may be formed by:
s10: defining a plurality of electrochromic regions on one side of the first electrode layer far away from the first substrate by using glue
According to an embodiment of the invention, in this step a plurality of electrochromic areas is defined on the side of the first electrode layer facing away from the first substrate by means of glue. In particular, referring to fig. 4, a plurality of
According to an embodiment of the present invention, the glue may be in contact with the electrochromic material applied to the electrochromic region in the subsequent step and the electrolyte layer prepared in the subsequent step, and in order to avoid the glue affecting the performance of the electrochromic material and the electrolyte layer, the glue may be selected from at least one of an optical glue, a polycarbonate glue and a polyethylene terephthalate glue. Therefore, the glue does not react with the electrochromic material and the electrolyte layer, and the performance of the electrochromic material and the performance of the electrolyte layer are not affected.
S20: forming a first electrochromic block
According to an embodiment of the invention, in this step, a first electrochromic lite is formed. According to an embodiment of the invention, the first electrochromic block is formed by first masking with a cover plate on the side of the glue remote from the first electrode layer, exposing only one electrochromic area, and subsequently applying the electrochromic material to the exposed electrochromic area. Therefore, the electrochromic color block can be formed by a simple process, and the production efficiency is higher.
The specific location of the cover plate is not particularly limited as long as the electrochromic material is not coated into the electrochromic regions of the cover, and a certain gap may exist between the cover plate and the glue in a direction perpendicular to the glue, thereby facilitating the removal of the cover plate. According to other embodiments of the present invention, in order to further prevent the electrochromic material from being coated into the covered electrochromic regions, the cover plate may also be in contact with the glue, and the glue defining the plurality of electrochromic regions may be subjected to a pre-curing treatment before the cover plate is disposed, so that the glue is cured to a certain extent to a non-flowable state. For some glue which can increase viscosity after being cured, the viscosity of the glue can be properly increased through the pre-curing treatment, so that the glue and the cover plate have good adhesion, the covered electrochromic area is sealed, the electrochromic material is prevented from being coated in the covered electrochromic area, and the generation of color mixing is avoided.
According to the embodiment of the invention, when the glue is an optical glue, the pre-curing treatment can be that the optical glue is cured to a state with good viscosity and difficult flowing by irradiating the optical glue with ultraviolet light. When the glue is polycarbonate glue or polyethylene terephthalate glue, the pre-curing treatment can be to cool the glue so that the glue is cured to a state of good viscosity and difficult flowing. Therefore, the glue after the pre-curing treatment can well adhere to the cover plate and seal the covered electrochromic area.
S30: forming another electrochromic block
According to an embodiment of the invention, in this step, a further electrochromic block is formed. According to an embodiment of the present invention, the covering position of the cover plate is first changed to expose another electrochromic area, and then an electrochromic material is coated in the exposed electrochromic area, thereby forming another electrochromic block. Specifically, the prepared electrochromic blocks and the electrochromic areas which are not coated with electrochromic materials are covered by the cover plate, and one electrochromic area which is not coated with electrochromic materials is exposed, so that the electrochromic materials are coated on the area to form another electrochromic block.
According to an embodiment of the present invention, when there is no adhesion between the cover plate and the glue, i.e. there is a gap between the cover plate and the glue, the cover plate is moved directly in this step. According to other embodiments of the present invention, when the cover plate is bonded to the glue, after the applying of the electrochromic material, the glue is subjected to a second curing process to further cure the glue and reduce the viscosity of the glue, thereby facilitating the cover plate to be removed from the glue. The specific operating parameters of the second curing process may be determined according to the specific type of glue, which may be, for example, a heating process. The specific temperature for the heat treatment is not particularly limited as long as the cover sheet can be peeled off from the glue and the glue is kept in a state of not easily flowing.
S40: repeating the above steps for multiple times to form multiple electrochromic blocks
According to an embodiment of the invention, in this step, a plurality of electrochromic tiles are formed. According to the embodiment of the invention, the steps are repeated for a plurality of times, that is, the operations of changing the covering position of the cover plate and coating the electrochromic material are repeated, so that the electrochromic material is coated in the plurality of electrochromic regions, and finally, the glue is subjected to the first curing treatment, so that the glue wall is formed, and a plurality of electrochromic color blocks are obtained.
According to the embodiment of the invention, the glue is subjected to the first curing treatment so as to enable the glue to reach a completely cured state, and the glue obtains certain hardness so as to obtain the glue wall. As described above, when the glue is an optical glue, the first curing process may be performed by irradiating the optical glue with ultraviolet light, and when the glue is a polycarbonate glue or a polyethylene terephthalate glue, the first curing process may be performed by cooling the glue.
According to the embodiment of the invention, in the step of forming the electrochromic color blocks, the electrochromic materials in the electrochromic color blocks are not completely the same, and the electrochromic colors of the electrochromic color blocks are not completely the same, so that the formed electrochromic layer can be ensured to simultaneously present multiple colors, and different colors can be formed when the voltage is changed, thereby further enriching the color effect of the electrochromic device.
According to an embodiment of the present invention, before the covering with the cover plate in the process of forming each electrochromic block, the glue may be subjected to a second curing process to make the glue have good adhesiveness, and when the covering is performed, the glue and the cover plate may have good adhesiveness to seal the covered electrochromic regions, preventing the electrochromic material from being coated into the covered electrochromic regions. After the electrochromic material is coated, the glue is subjected to second curing treatment, so that the cover plate can be conveniently removed from the glue, and a next electrochromic block can be conveniently prepared. Therefore, the generation of color mixing can be avoided, and the formed electrochromic device can display vivid colors.
According to the embodiment of the invention, in order to ensure that the thickness of the electrochromic layer is uniform, the thickness deviation between two adjacent electrochromic blocks does not exceed 10 nm. Thus, the electrochromic layer has a uniform thickness and good color change stability.
S200: a second electrode layer, an ion storage layer and an electrolyte layer sequentially arranged on the second substrate
According to an embodiment of the present invention, in this step, a second electrode layer, an ion storage layer, and an electrolyte layer are sequentially provided on a second substrate. According to an embodiment of the present invention, a second substrate is first provided, and the second substrate may be formed of glass or plastic. Thereby, the color of the electrochromic device can be transmitted out of the second substrate. According to an embodiment of the present invention, when the second substrate is formed of plastic, it may be formed of polyethylene terephthalate or polycarbonate. Thus, the cost of the electrochromic device can be further reduced.
According to an embodiment of the invention, a second electrode layer is then formed on the second substrate by sputtering. Specifically, when the second substrate is formed of glass, the second electrode layer may be formed by high-temperature sputtering, and when the second substrate is formed of plastic, the second electrode layer may be formed by low-temperature sputtering. Thus, the second electrode layer can be formed on the second substrate by a simple method. The specific temperature for sputtering is not particularly limited, and may be designed according to the applicable temperature of the specific material constituting the second electrode layer. Regarding the constituent material of the second electrode layer, the detailed description has been made above, and the description is omitted here.
According to an embodiment of the present invention, an ion storage layer is then formed on the second electrode layer on a side away from the second substrate. Specifically, the ink containing the polymer of the ion storage layer can be uniformly coated on the side of the second electrode layer away from the second substrate by spin coating, curtain coating, roll coating, blade coating, dip coating, spray coating or silk screen printing to form the ion storage layer.
According to an embodiment of the invention, an electrolyte layer is then formed on the side of the ion storage layer remote from the second electrode layer. Specifically, the electrolyte layer can be uniformly coated on the side of the ion storage layer far away from the second electrode layer by means of screen printing. According to the embodiment of the present invention, the electrolyte layer is made of a gel material, and particularly, the electrolyte layer may include a gel material, a plasticizer, conductive ions, and a solvent. Compared with liquid electrolyte, the electrolyte layer formed by the colloidal material has the advantages of high stability, long service life and the like, and can not generate the bad phenomena of bubbling or electrolyte leakage and the like, thereby further prolonging the service life of the electrochromic device.
S300: packaging a first substrate provided with an electrochromic layer and a second substrate provided with an electrolyte layer
According to an embodiment of the present invention, in this step, the first substrate provided with the electrochromic layer and the second substrate provided with the electrolyte layer are encapsulated, and the electrochromic layer is brought into contact with the electrolyte layer, so that an electrochromic device is formed. According to an embodiment of the present invention, the encapsulation process may be implemented by: and arranging insulating glue on the peripheries of the electrochromic layer, the electrolyte layer and the ion storage layer, and oppositely arranging the first substrate and the second substrate, and connecting the first substrate and the second substrate through the insulating glue. Thereby, the electrochromic layer can be sealed and insulated from interference from the external environment. Or, the electrochromic layer is directly attached to the electrolyte layer by utilizing the characteristic that the electrolyte layer has certain viscosity (as mentioned above, the electrolyte layer is formed by colloidal materials), so as to complete encapsulation and form the electrochromic device.
Specifically, a first electrode layer and an electrochromic layer may be sequentially disposed on a first substrate, and then a second electrode layer, an ion storage layer, and an electrolyte layer may be sequentially disposed on a second substrate; alternatively, the second electrode layer, the ion storage layer, and the electrolyte layer may be provided on the second substrate in this order, and then the first electrode layer and the electrochromic layer may be provided on the first substrate in this order. That is, the order of forming the first substrate and the second substrate having each layer structure is not particularly limited as long as the structures to be formed are formed on the two substrates (including the first substrate and the second substrate) before the encapsulation, respectively.
According to the embodiment of the invention, at least one of the first substrate and the second substrate is provided with the optical adhesive layer on the side far away from the electrochromic layer, and the optical adhesive layer is provided with the release film layer on the side far away from the electrochromic layer. Therefore, the electrochromic device can be independently stored, is convenient to assemble with the shell substrate, and simplifies the preparation process of the shell. According to the specific embodiment of the invention, when the first electrode layer is made of the transparent material and the second electrode layer is made of the metal material, the optical adhesive layer is only arranged on one side of the first substrate far away from the electrochromic layer, and then the first substrate and the housing substrate are attached together by the optical adhesive layer in the process of assembling the housing, so that the operation is convenient and the cost is low. According to other embodiments of the present invention, when the first electrode layer is formed by a metal material and the second electrode layer is formed by a transparent material, the optical adhesive layer is disposed only on a side of the second substrate away from the electrochromic layer, and then the second substrate and the housing substrate are attached together by the optical adhesive layer in a process of assembling the housing.
