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)ethyl-methacrylate (DMAEMA), followed by betainisation with 1,3-propanesultone. By UV irradiation, transparent PSH# films could be prepared on the silicon- wafers by spin-coating. The films having a larger amount of bactericidal HCPM unit showed higher bactericidal activity which means 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. The PSH#s films could be applied as an antibacterial coating materials. |
