Problems solved by technology

[0007] At present, the research on the antimicrobial properties of borneol only stays in the modification of the substrate by using borneol alone, and has a significant antibacterial effect. However, the photoinitiated polymerization of the borneol acrylate monomer cannot realize the modification of the surface of the material. Antibacterial performance (see comparative example)
[0008] In addition, the aforementioned patent modification method is limited to groups with high reactivity, and the operation steps are relatively complicated, which will lead to unnecessary waste of resources in the production process

Abstract

The invention relates to a non-release type antimicrobial adhesion coating and a preparation method thereof. A polymer forming the coating is formed by copolymerization of two monomers, namely bornyl acrylate and polyethylene glycol diacrylate; and the coating has good antimicrobial adhesion. The preparation method of the coating mainly comprises the following steps: firstly, preparing a solution with a certain concentration from the monomers and a photoinitiator, and then carrying out two-step modification on a high polymer material by using a photo-grafting method, wherein in the first step, the is photoinitiator fixed on the surface of the high polymer material, and in the second step, surface free radical-initiated polymerization is conducted on the monomers to realize grafting. The preparation method of the coating is simple, and the obtained grafted coating is safe and stable; respective advantages of the bornyl polyacrylate and the polyethylene glycol diacrylate can be fully exerted, and microbial adhesion can be synergistically prevented; and the coating can be applied to surface modification of most high polymer materials, and the structural flatness of the grafted coating can be ensured.

Description

technical field [0001] The invention belongs to the field of biological materials, in particular to a non-releasing anti-microbial adhesion coating and its preparation method and application. Background technique [0002] Polymer film or sheet is widely used in people's life and industrial production, such as agriculture, food, medical treatment, chemical industry, etc. However, these polymers usually do not have the function of anti-microbial adhesion, which provides a medium for the adhesion and spread of microorganisms, seriously affects the efficiency of production, and threatens human health. These microbial contamination problems have attracted more and more attention from researchers in recent years. Therefore, it is of great significance to modify the surface of polymers to endow them with anti-microbial adhesion properties without destroying the internal structure of polymers. [0003] The current preparation methods of polymer antibacterial materials are mainly di...
