A series of copolymers (PSH#s, where # is the molar ratio of zwitterionic monomer, sulfobetaine methacrylate (SBMA)) containing both plant-based cardanol and zwitterionic moieties was synthesized via free radical polymerization of 2-hydroxy-3-cardanylpropyl methacrylate (HCPM) and (dimethylamino)ethylmethacrylate (DMAEMA), followed by betanisation with 1,3-propanesultone. Transparent PSH# films could be prepared on the silicon- wafers by spin-coating and UV-crosslinking process. The films having a larger amount of bactericidal HCPM unit could more effectively kill the bacteria, while the adhesion resistance to biofoulants was dramatically enhanced with increasing more hydrophilic SBMA unit. Moreover, all the films showed sufficient biocompatibility regardless of the ratio of HCPM and SBMA units.
