A series of copolymers, which contains zwitterionic moieties and natural-derived antibacterial cardanol was synthesized and named as PSH#s where # is the molar ratio of sulfobetaine methacrylate (SBMA), the zwitterionic monomer. PSH#s were successfully prepared by free radical polymerization of (dimethylamino)ethyl methacrylate (DMAEMA) and 2-hydroxy-3-cardanylpropyl methacrylate (HCPM), and betanisation with 1,3-propanesultone. PSH#s were dissolved in chloroform to obtain transparent films by spin coating on the silicon wafer and crosslinked by UV-irradiation. The films exhibit more effective antibacterial property with increasing amounts of antibacterial HCPM unit, while biofoulants were interrupted to adhere on the films with larger amount of hydrophilic SBMA unit. Moreover, all of these films were found to have sufficient biocompatibility regardless of the ratio of HCPM and SBMA units.
