Technical Field

The invention belongs to the technical field of biological medicines, relates to an antibacterial and antiviral material technology, and particularly relates to an antibacterial and antiviral micro-nano structure flexible film and application thereof.

Background

Microorganisms, viruses and the like can be attached to and deposited on the surface of an object, and grow and propagate on the surface of the object to form a pollution source or pathogenic bacteria, which can threaten the health of the human body.

At present, the antibacterial and antiviral of the surface of an object are mainly carried out by adopting a chemical method, such as: the disinfectant of bleaching agent, ammonia and other common cleaning agents is used for disinfecting and sterilizing the surface of an object, however, the use of the disinfectant can cause secondary pollution on the surface of the object, and the discharge of the disinfectant can cause certain environmental pollution. Some antibacterial materials are also used in the market, and the antibacterial and antiviral effects are also carried out on the surface of an object through chemical action, and the antibacterial materials are mainly prepared by mixing antibacterial substances or antibacterial coatings in the materials and sterilizing the surface of the object through the antibacterial substances or the antibacterial coatings. However, most of the mixed antibacterial substances are chemical substances, and the uncontrollable release of the chemical substances in the using process can cause potential danger to users; the antibacterial coating can gradually fall off under external environments such as high temperature, high humidity and the like, and further loses the antibacterial and antiviral functions.

At present, there is also an application of designed antibacterial film, the action mechanism of which is to reduce the adhesion of pathogenic bacteria on the surface of an object by a physical method, the antibacterial film mostly adopts a nano structure, but the existing antibacterial film with a nano structure has a larger or smaller bacteria inhibiting capability, and once a few bacteria are attached to the surface of the object, the bacteria still grow and propagate rapidly.

Therefore, it is necessary to design a new antibacterial film capable of reducing adhesion of germs to the surface of an object.

Disclosure of Invention

The invention aims to design an antibacterial and antiviral micro-nano structure flexible film, the micro-nano structure flexible film adopts the flexible film with the micro-nano structure to carry out antibacterial and antiviral on the surface of an object, and the antibacterial and antiviral action mechanism is to reduce and prevent germs, viruses and other microorganisms from attaching to the surface of the object. Meanwhile, when a small amount of microorganisms are attached to the micro-nano structure of the flexible film, due to the special design of the micro-nano structure (such as a composite functional layer and other structures), the growth and the propagation of the microorganisms are inhibited, and the surfaces of microbial cells or viruses are damaged, so that the aims of resisting bacteria and viruses are fulfilled. The micro-nano structure flexible film has wide application range, can be used on the surfaces of equipment such as medical instruments and the like, and can be adhered to or implanted into the surfaces of organisms and the like.

The technical scheme for realizing the purpose of the invention is as follows: the utility model provides an antibiotic and antiviral micro-nano structure flexible film, includes flexible thin film layer, and the upper surface processing of flexible thin film layer has first micro-nano structure, and the lower surface of flexible thin film layer is equipped with compound functional layer.

The test assembly of the composite functional layer can monitor the state of the environment where the flexible thin film layer is located in real time, assist the flexible thin film layer to resist bacteria and inhibit bacteria, and improve the antibacterial and antiviral effects of the flexible thin film layer.
