A series of copolymers 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 post modification with 1,3-propanesultone. Transparent PSH# films could be prepared on the silicon- wafers by spin-coating and UV-crosslinking process. The bactericidal and antifouling properties of the polymer films were found to be closely related to the ratio of HCPM and SBMA units in the copolymers. 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. |
