Biological antibacterial and antifouling low surface energy coating with surface micro-structure and preparation method of biological antibacterial and antifouling low surface energy coating

Abstract

The invention discloses a biological antibacterial and antifouling low surface energy coating with a surface micro-structure and a preparation method of the biological antibacterial and antifouling low surface energy coating. The antibacterial and antifouling coating comprises a microemulsionprepolymerizationsolution prepared from raw materials as follows: a fluorine-containinglow surface energy monomer, an acrylate monomer, a hydantoinderivative, an emulsifying agent, a co-emulsifier, an ammonia solution and tetraethoxysilane. The antifouling coating not only has anti-adhesion low surface energy hydrophobic nature, has a sterilization functionsimultaneously, can simultaneously resist protein adsorption and bacterial adhesion and has a double-protection function to delay formation of a biological film on the surface of a coating, so that growth and breeding of large-scale living organisms such as microalgae and the like on the coating surface are slowed down; the antifouling coating is prepared with a one-step microemulsion polymerizationmethod, can effectively prevent volatilization pollution of organic solvents, doesn't release toxic substances simultaneouslyand has the characteristics of environment-friendliness and safety; and the preparation method is simple and convenient, and film forming is fast.

Description

technical field

[0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to a low surface energy coating with a surface microstructure and a preparation method thereof, which has synergistic effects of antifouling and sterilization. Background technique

[0002] In many practical applications, from biomedical devices, reservoirs, underwater facilities to ships, how to resist the adhesion of non-specific biomolecules and microorganisms on the surface and improve the anti-bioadhesion ability of the surface is a big challenge. . For example, non-specific protein adsorption on the surface of biosensors can lead to poor performance, resulting in inaccurate detection or diagnosis; non-specific protein adsorption can negatively affect the treatment and repair of artificial organs or orthopedic implants; The adhesion and growth of the inner wall of the water pipe and the wall and bottom surface of the pool or swimming pool will m...
