Zwitterionic systems are known for their strong antifouling effect and they readily resist adsorption of proteins1 and a large range of freshwater and marine fouling organisms2-3. The low fouling properties are in general ascribed to the net charge neutrality of zwitterionic materials, and the selection of anionic and cationic groups allows to tailor the coatings for specific applications. As only a handful of zwitterionic monomers are commercially available, sulfobetaines and carboxybetaines are frequently studied systems4-5. We extend the range of accessible polymers and explore the next generation of polymers with advanced functionality.
