To improve sufficient antifouling properties, zwitterionic materials have been proposed as new generation materials to inhibit protein adsorption and formation of biofilm. Moreover, many studies have demonstrated that fluorinated materials have antifouling and antimicrobial effects. Here, we designed novel zwitterionic and tetra-fluorinated polyurethane (ZFPU) additives to confer anti-fouling and anti-thrombotiic effects and blended these with polyvinyl chloride (PVC). 1HNMR and FTIR analyses showed that the zwitterionic groups and fluorinated groups were successfully introduced onto the ZFPU backbone. We also investigated the protein adsorption, platelet adhesion and wettability of additives-blended PVC films. Our results demonstrated that the ZFPU additives-blended PVC surfaces significantly suppressed protein adsorption and platelet adhesion than those of pristine PVC surface. |
