A series of copolymers containing nature-derived cardanol and zwitterionic moieties was synthesized and named PSH#s where # is the molar ratio of zwitterionic monomer, sulfobetaine methacrylate (SBMA). PSH#s were prepared by free radical polymerization of 2-hydroxy-3-cardanylpropyl methacrylate (HCPM) and (dimethylamino)ethyl methacrylate (DMAEMA), followed by betanisation with 1,3-propanesultone. Transparent PSH# films were obtained on the silicon wafer by spin coating and crosslinked by UV irradiation. The films having a larger amount of bactericidal HCPM unit show more efficient bactericidal effect, while the adhesion of biofoulant was interrupted dramatically with increasing amount of hydrophilic SBMA unit. Moreover, all the films satisfied sufficient biocompatibility regardless of the ratio of HCPM and SBMA units. |
