Referring to FIG. 1, enhancing the serialization of metal-base composites for the two-dimensional material of the embodiment of the invention The flow diagram of preparation method.

The preparation method of the metal-base composites includes the following steps:

S101: using roll-to-roll chemical vapor deposition process, deposits single-layer or multi-layer two-dimensional material, shape in metal foil surface At composite insulating foil.

Roll-to-roll chemical vapor deposition (roll-to-roll chemical the vapor deposition, R2R CVD) can serialization prepare film.The R2R CVD equipment mainly includes five half parts, be respectively gas supply system, Vacuum system, high-temperature systems, to volume system and cooling system.Wherein, gas supply system mainly provides deposition gas source (such as CH₄、C₂H₂Deng), Ar and H₂Deng；Vacuum system is vacuumized by vacuum pump；Heating and cooling system of the high-temperature systems by sequencing System control；Metal foil movement speed control is then carried out to volume system；Cooling system is mainly to multiple after the completion of two-dimensional material is grown It closes foil and is rapidly cooled processing.

Referring to FIG. 1, the partial schematic diagram of the depositing device for roll-to-roll chemical vapor deposition process, roll-to-rollization Learn gas-phase deposition include tube furnace 101, be located at 101 two sides of tube furnace to volume input terminal 102 and to roll up it is defeated Outlet 103.The input terminal 102 and output end 103 respectively include rotatingcylindrical drum, and continuous metal foil 201 is covered in input On the roller at end 102, is rotated by conveyer belt transmission and roller, metal foil 201 is sent into tube furnace 101, carry out two dimension The deposition of material forms composite insulating foil 105 and exports from the other end of tube furnace 101, is covered on the roller of output end 103, can be with Realize the preparation of serialization.

By movement speed of the control metal foil in tube furnace 101, that is, realize the control to two-dimensional material growth time, together When adjust tube furnace in pressure, the adjustment to the two-dimensional material number of plies may be implemented.

The material of the metal foil 104 includes the transition metal with catalytic activity, such as Ni, Ru, Co etc..The metal It can also be low-melting-point metal, such as Al.

The two-dimensional material can be graphene, BN or MoS₂Deng.

It, can be with using plasma assisting growth, to improve two during carrying out roll-to-roll chemical vapor deposition The growth efficiency of material is tieed up, the metal species that can be used as growing substrate are expanded.

In order to improve metal foil surface two-dimensional material growth result, the metal foil can be made annealing treatment, The impurity of metal foil surface is attached to reduce roughness and the removal of metal foil surface.

S102: in deposition process, by roll-to-roll transmission, the composite insulating foil is successively covered in depositing device one end In internal model.

The roller 103 of output end can be used as to internal model, the interior mold materials can be stainless steel, can be according to be formed Composite material size, select the internal model of suitable dimension.

Rolling up the number of plies covered can be adjusted according to the thickness of composite material to be formed, and the number of plies is more, and thickness is bigger.

S103: it completes to roll up the composite insulating foil outer cladding external mold covered, and is carrying out vacuumize process.

Internal model 201 is removed together with the composite insulating foil 202 being covered in thereon, coats external mold 203 (please referring to Fig. 3) outside, And vacuumize, so that being fitted closely between internal model 201, composite insulating foil 202 and external mold 203.

S104: the composite insulating foil is subjected to hip treatment, is cooled to room temperature, reguline metal based composites are obtained.

By hip treatment, the compactness between 202 single layer of composite insulating foil and each layer can be improved, improve two-dimensional material Interface binding power between metal foil.And it improves and arranges the depth of parallelism between two-dimensional material and metal foil, improve two-dimensional material Characteristic in its two-dimensional surface, to improve two-dimensional material to the improvement effect of whole metal-base composites characteristic.

Hereinafter, illustrating the two-dimensional material reinforced phase by taking the Cu-base composites for forming graphene enhancing as an example The preparation method of metal-base composites.

Firstly, by long 400m, wide 60mm, with a thickness of 25 μm of industrial cold rolling Cu foils at 1000 DEG C, H₂Under protective atmosphere into Row annealing 30min processing, and annealing Cu foil is collected in the output end to volume.Annealing using R2R CVD equipment into Row, anneals in tube furnace, is convenient for collecting the rolling of Cu foil.In other specific embodiments, the Cu foil Length can be in 100m~400m, width is 60cm~100cm, and specific size is according to the diameter of tube furnace and to be formed Depending on the size of metal-base composites.

Then, Cu foil after annealing is placed in the input terminal to volume, gaseous carbon sources and current-carrying gas is then passed to, appropriate The high growth temperature of single layer Gr is carried out under gas ratio.Specifically, adjusting the gas in tube furnace after tube furnace is warming up to 1000 DEG C Body flow is 200sccm CH₄With 6sccm H₂, and vacuum is evacuated to 1Torr or so using vacuum pump, it carries out with this condition single The growth of layer graphene (Gr).It adjusts to volume speed, makes Gr in the growth time 30min of tube furnace flat-temperature zone.Utilize circulation Cooling water system is rapidly cooled to room temperature the Cu foil for having grown single layer Gr from high temperature, and then obtains single layer in the output end to volume The composite insulating foil of Gr/Cu.

Referring to FIG. 4, wherein (a) is the photo for having grown the Cu foil of Gr of single layer.(b) for the change of Cu foil surface distance Change, the peak 2D of Gr and the ratio (I at the peak G_2D/_IG) and the peak 2D peak width at half height variation (FWHM), it can be seen that single layer Gr covering More uniformly.(c)~(e) is respectively that figure is swept in the face Raman of Cu foil monolayer surface Gr；(f) difference to be irised out in (c)~(e) Raman map at position, avoids position from all grown Gr.At the different location of Cu foil surface, the Raman of single layer Gr (Raman) I2D/IG changes between 2.8~4.0, and the peak width at half height at the peak 2D is between 28~34, it was confirmed that single layer Gr itself High quality and high uniformity.From FIG. 4, it can be seen that can be in Cu foil using above-mentioned roll-to-roll chemical vapor deposition process The upper uniform single layer Gr of growth.

Inventors have found that passing through gas ratio (the mainly CH in fixed Gr growth course₄And H₂), gradually increase growth Pressure is, it can be achieved that H₂To " intrusion " effect of the edge Gr carbon-coating, the synchronous deposition of multilayer carbon atom is realized, and then realize multilayer Gr Growth.On the basis of growing single layer Gr, it can continue to keep CH₄And H₂Flow it is constant, gradually increased by Manual pressure valve Add the pressure in tube furnace from 1Torr to 500Torr, to realize the Gr number of plies from single layer to about ten layers of controllable growth.Multilayer The growth temperature of Gr is still 1000 DEG C, growth time 30min.The Raman of different number of plies Gr is characterized as shown in figure 5, due to life The increase of long pressure, H₂The etching power of agraphitic carbon is reduced, so that starting defect peak (D occur when the Gr number of plies is eight layers Peak).

Referring to FIG. 6, figure is swept in the face Raman that (a-c) is two layers of Gr；It (d) is to be corresponded at different location in (a-c) figure Raman map.Figure is swept by the face Raman of bilayer Gr in Fig. 6 it is found that the coverage rate of bilayer Gr is still above~90%.

Referring to FIG. 7, (a) is the scanning pattern of 5-6 layers of Gr/Cu；(b) the scanning pattern for being 10 layers of Gr/Cu.For 5-6 Gr/Cu and 10 layer of Gr/Cu of layer, since the growth pressure of Gr increases, H2 reduces carbon atom etching power, so that the coverage rate of Gr It decreases, but the coverage rate of 5-6 layers of Gr is still maintained at 85%, and not only quality decline (is corresponding with and is independently distributed 10 layers of Gr Amorphous carbon occurs), coverage rate is also down to 75%.

In other specific embodiments, graphene is deposited on the Cu foil using roll-to-roll chemical vapor deposition process Pressure be 1Torr~500Torr, temperature be 800 DEG C~1000 DEG C, growth time be 20~30min.It can be according to specific Equipment, Gr quality requirement, deposit the Gr of the reasonable number of plies.

By the setting and adjusting to Gr gas flow and growth pressure during the growth process, single layer may be implemented to about ten Layer Gr being precisely controlled in the Cu foil surface number of plies, quality and coverage rate.

Then, coat stainless steel mould outside the Gr/Cu composite insulating foil that covers of multilayer volume with stainless steel internal model, then into Row vacuumize process.After vacuumizing, composite insulating foil is placed in hot isostatic pressing (hot isotropic pressing, HIP) In the cabin of sintering furnace.900 DEG C are risen to the heating rate of 10 DEG C/min, 1h is then sintered under the pressure of 100MPa, finally Cool to room temperature with the furnace again.Wherein, the diameter of internal model is 80mm, outer mode diameter 90mm.The temperature of the HIP processing cannot mistake Height avoids the fusing of Cu foil, and the temperature of the HIP can not be too low, and temperature is too low to be had effect.It is specific real at other It applies in mode, the temperature of the hip treatment can be 850 DEG C~950 DEG C, and pressure can be 50MPa~100MPa, when Between be 30min~1h.

Referring to FIG. 8, using the internal model and external mold of demoulding equipment removal Gr/Cu composite insulating foil, just being obtained after to HIP The Gr/Cu block composite material of circular configuration.

During growing Gr, by the number of plies for controlling Gr, it will be able to which the Gr/Cu block for obtaining the different Gr numbers of plies is compound Material, to meet the needs of different.

Currently, being concentrated mainly on powder metallurgy using the preparation method of Gr enhancing MMCs heating conduction.The shortcomings that the method The strong―binding interface and Gr difficult to realize for being mainly reflected in the high quality for being unable to ensure Gr itself, Gr and metallic matrix are in gold Belong to parallel, the parallel arrangement in matrix, and then is difficult to play the feature of high thermal conductivity in its face.Secondly, existing powder metallurgy system Standby technology is difficult to realize the extensive of Gr/ metallic composite, serialization preparation.

Referring to FIG. 9, wherein (a) is the cross-sectional scans pattern of single layer Gr/Cu, apparent layer structure, explanation are shown Gr height parallel arrangement；(b) be (a) enlarged drawing；It (c) is graphene nanometer sheet (graphene in existing powder metallurgical technique Nanoplates, GNPs) scanning figure, graphene nanometer sheet is difficult to realize height parallel arrangement.

It can be seen that roll-to-roll depositing operation through the invention enables to Gr Parallel Growth in Cu foil surface, it is subsequent It is handled again by HIP, so that Gr and the further dense arrangement of Cu, improve the depth of parallelism of Gr, to improve the matter of Gr itself Interface bond strength between amount and Gr and Cu matrix, gives full play to the feature of high thermal conductivity in its face.

A large number of studies show that the Gr of self-supporting high quality just has a heating conduction in high face, the defects of Gr, strain, The presence of fold and functional group will lead to the decline of Gr itself heating conduction.Thus it is guaranteed that the high quality of Gr is to realize that height is led The premise of hot MMCs.And Gr in the market is mostly the presence in the form of its derivative, including redox graphene instantly (reduced graphene oxide, RGO), graphene nanometer sheet (graphene nanoplates, GNPs) and graphene paper (graphene paper,GP).So relative high quality Gr, the heating conduction of these derivatives itself has declined more, nothing Method guarantees high thermally conductive reinforcing efficiency.At the same time, due to the big face Gr it is wide than, the strong Van der Waals for of interlayer, big table Face energy and the larger difference with metallic matrix density, so that Gr easily reunites in metallic matrix.At this point, researcher is on the one hand Surface modification treatment is carried out to Gr, on the other hand the method for high-energy ball milling is also mostly used to carry out in metallic matrix powder to Gr in advance Dispersion, however the two all will inevitably cause the destruction of Gr high crystalline, to reduce the heating conduction of composite material.And And existing complex method belongs to that metallic matrix will be added to outside reinforced phase, the interface cohesion between Gr and metallic matrix usually compared with Weak, this greatly reduces the effect of the phonon coupling at Gr/ metal interface.Although part researcher is adopted by flakelike powder metallurgy With solid carbon source in the sheet spontaneous Gr of Cu powder surface in situ to improve its quality and its interface cohesion between Cu matrix, but gained The Gr uniformity arrived is poor, often results in the uncontrollable of heating conduction.

And the method that the present invention uses CVD vapor deposition, Gr is deposited in Cu foil surface first under ultra-high vacuum environment, The regulation for not only realizing Gr high quality and the number of plies, the coherent boundary for also achieving Gr (0001) and Cu (111) face combine, thus Interface bond strength between the two is improved, interface strain is reduced, and then promotes the effect of the interface Gr and Cu phonon coupling It improves, finally reduces interface resistance.

Referring to FIG. 10, wherein (a) is that the XRD of the Cu foil of single layer Gr/Cu during the preparation process composes variation；It (b) is annealing The EBSD figure of Cu foil shows strong (100) texture；(c) after showing Gr growth for the EBSD of single layer Gr/Cu, there is high-volume fractional (111) Cu being orientated；(d) it is the EBSD of the single layer Gr/Cu block composite material after HIP process, illustrates block materials (111) are orientated by force.

It can be seen that HIP is handled, so that the copper of block materials generates strong (111) orientation, the crystal lattice orientation one with Gr It causes.

Figure 11 is please referred to, is the strain characterization at single layer Gr/Cu coherent boundary.Above-mentioned specific embodiment realizes realization Gr (0001) and the coherent boundary in Cu (111) face combine (as shown in Figure 5), thus it is strong to improve interface cohesion between the two Degree reduces interface strain, and then promotes the raising of the interface Gr and Cu phonon coupling effect, finally reduces interface resistance.At this In the specific embodiment of invention, the interface Gr and Cu is able to achieve 80% or more coherent boundary.

Gr improves the heating conduction of MMCs, essentially consists in the characteristic for giving full play to high thermal conductivity in its face, and according to above-mentioned interior Hold, Gr easily reunites again in metallic matrix, therefore realizes that the height of Gr in the composite is arranged in parallel most important.This hair It is bright that circular Gr/Cu composite insulating foil can be obtained in the output end to volume first by way of R2R CVD, then pass through the later period HIP densification process can obtain the block composite material of parallel, the arranged in parallel Gr/Cu of Gr height.Moreover, serialization The preparation of Gr/Cu composite insulating foil can also promote the extensive of block Gr/Cu composite material, serialization preparation.

In conclusion relative to the Gr faced in existing PM technique preparation high thermal conductivity Gr/ metallic composite It is of low quality, Gr/ metal interface bond strength is not high, Gr be difficult to realize height parallel arrangement and composite material be difficult to advise greatly Difficult point prepared by mould, serialization, the present invention is not only able to achieve the controllable preparation of high quality Gr using R2R CVD, and can promote Gr/ The formation of Cu coherent boundary.Moreover, while realizing that Gr is highly arranged in parallel in the composite, and realize the big of MMCs Scale serialization preparation.Finally, thermal conductivity reaches (393.87 ± 5.49) W/mK in the face of 5-6 layers of Gr/Cu composite material, is higher by phase Thermal conductivity about 22% in the pure face Cu being prepared with technique.

It, can also be in other transition metal with catalytic activity other than Cu matrix in other specific embodiments The block of corresponding Gr height parallel arrangement can be prepared in matrix such as Ni, Ru, Co etc. by the technique of R2R CVD combination HIP Composite material.

, can also be using the method for plasmaassisted growth Gr in other specific embodiments, and combine R2R CVD And subsequent HIP technique, Gr can be grown in low-melting-point metal, such as 600 DEG C of the surface Al, deposition 30min, can be prepared simultaneously Lightweight, high-strength Al based composites.

Further, it in other specific embodiments, can also be can further improve by the thickness of reduction metal layer Volume fraction of the Gr in MMCs, to preferably improve the comprehensive performance of composite material.

In other specific embodiments, also can use R2R CVD combination HIP technique is continuous, large scale preparation other The MMCs of two-dimensional material enhancing deposits BN under the conditions of 1000 DEG C of temperature, sedimentation time 30min such as in Cu matrix, recycles HIP prepares block BN/Cu composite material, to improve the dielectric constant of composite material；For another example MoS is utilized₂Enhance MMCs, can be improved The greasy property etc. of MMCs.

A specific embodiment of the invention also provides a kind of metal-base composites, comprising: multiple dense is stacked as bulk Composite insulating foil, the composite insulating foil includes metal foil and the single-layer or multi-layer two-dimensional material for being deposited on the metal foil surface；Institute State metal foil and the spaced and parallel arrangement of the two-dimensional material.
