Abstract
The present invention provides a method for preparing an antibacterial and low-adhesion cross-linked polyvinyl alcohol coating. A simple two-step method is adopted, wherein polyfunctional isocyanate is first used to strongly cross-link with the hydroxyl group of polyvinyl alcohol, and then a compound with low surface energy such as mono-hydroxyl silicone oil or the like is received in to effectively reduce the surface energy of the surface of the coating; and two structure-function relationships are efficiently synergistic through effective strong cross-linking and regulation of the compound with low surface energy within the system, enabling the strongly cross-linked polyethylene coating to have excellent performance of water adhesion resistance and oil adhesion resistance, and good performance of bacterial adhesion resistance, which is expected to be applied in the fields of materials for antifouling and self-cleaning, liquid transportation and implantation in animal body.
