Amphiphilic materials for advanced antifouling and anticorrosion coatings

Abstract

Biofouling, the accumulation of microorganisms on submerged surfaces, poses significant challenges to the environment and human activities. The widespread use of toxic antifouling coatings, such as those containing tributyltin, has led to their progressive ban worldwide due to environmental concerns. As a promising alternative, polymer-based antifouling coatings have gained attention due to their affordability, non-toxicity, biocompatibility, and ease of production. We focus here on the research progress in environmentally friendly amphiphilic antifouling coatings, focusing on silicone-based coatings, fluoropolymer-based coatings, PEG-based coatings, and zwitterionic coatings. Emphasis is placed on synthetic strategies, structural design principles, and functional properties that enhance antifouling performance. Consolidating current advancements and addressing challenges are serving researchers and industry professionals striving to develop innovative, sustainable antifouling solutions for diverse applications.
