The application of antibacterial coating technology is directly related to solving the problem of biological pollution and infection of medical devices, but the limitations of traditional modification methods are not enough to solve this problem. Therefore, the new antibacterial coating strategy pays more attention to the combined suppression of bacteria through multi-level mixing of materials and process improvement. Function. For example, the composite coating composed of chitosan derivatives and multi-metal oxides has the effect of temperature sensitivity and self-repair, which can ensure its ability to maintain antibacterial activity in various environments; the micro-absorption coating generated by two-step immersion of egg white protein and tannic acid can effectively reduce the adhesion and load-bearing of microorganisms. The continuous sterilization effect of nanosilver; the step-by-step precipitation method can form a continuous and tight chitosan coating on complex surfaces, providing physical barriers and biological activation; the superhydrophobic coating improves the anti-fouling performance through the nanometer-scale porous structure; the coating with high transmittance achieves the flatness between optical properties and antibacterial properties. Weigh. The future development direction focuses on the design of intelligent reaction, the application of environmental protection materials and the overcoming of the process standardization problem of clinical transformation, so that coating technology will develop in the direction of high efficiency, safety and multi-functional integration.
