Marine biofouling, the adhesion of marine organisms onto the ship hull, causes increased fuel consumption. Many attempts have been made to address the issue, and among them, antifouling polymer coating has been extensively investigated. Zwitterionic polymers have been frequently used for the surface coating, and the coatings have shown excellent marine antifouling performance. However, when the coatings are exposed to sediment, various minerals are easily adsorbed by the zwitterionic polymer coating. In this respect, amphiphilic polymer coatings have been considered as an alternative to hydrophilic polymer coatings. In this study, we report on the formation of amphiphilic copolymer brushes composed of sulfobetaine methacrylate and trifluoroethyl methacrylate by surface-initiated, atom transfer radical polymerization. The resulting surfaces are found to have excellent antifouling performance against both diatom adhesion and silt dsorption.
