Antifouling coating of a ternary crosslinking network and preparation method and application thereof

By designing a ternary cross-linked network structure and combining the principles of self-polishing and low surface energy, the resulting antifouling coating can effectively prevent the attachment of marine fouling organisms in both static and dynamic environments. This solves the problems of poor antifouling performance and insufficient mechanical properties of existing coatings, and achieves a long-lasting antifouling effect.

AI Technical Summary

⚠Technical Problem

Existing marine antifouling coatings suffer from poor antifouling performance, short antifouling duration, and insufficient mechanical properties.

⚗Method used

A ternary cross-linked network structure is adopted, which combines active capsaicin cross-linking monomers, capsaicin-modified hydroxystyrene-acrylic resin and dihydroxy-terminated polydimethylsiloxane to form a capsaicin-organosilicon-polyacrylate-based ternary cross-linked network, thereby achieving synergistic coupling of self-polishing and low surface energy, and enhancing antifouling performance and mechanical properties.

🎯Benefits of technology

It can effectively prevent the attachment of marine fouling organisms in both static and dynamic environments, extend the antifouling period, and improve the adhesion and antifouling effect of the coating, thus solving the problems of poor antifouling performance and insufficient mechanical properties of existing coatings.
