The flip-flop property of the amphiphilic polymer surfaces is especially useful to present ideal antifouling properties to materials by converting their hydrophobic surface to hydrophilic one when immersed in aqueous medium. We synthesized copolymers composed of zwitterionic carboxybetaine monomers and hydrophobic trimethylsiloxy groups as the amphiphilic copolymer and characterized the flip-flop properties and the antifouling abilities of the copolymer against hydrophilic and hydrophobic foulants. In addition, we investigated the antifouling properties of the zwitterionic flip-flop copolymer for the biological foulants. As a result, a significant decrease in cell adhesion was also observed, indicating that the surface modification by the zwitterionic flip-flop copolymer could be a universal antifouling technique in various environments such as ambient, aqueous, and biological environments. |
