To improve sufficient antifouling properties, zwitterionic materials have been proposed as new generation materials to inhibit protein adsorption and formation of biofilm. Moreover, it has been demonstrated that fluorinated materials have antifouling and antimicrobial effects. In this study, novel zwitterionic and tetra-fluorinated polyurethane (ZFPU) additives were blended with polyvinyl chloride (PVC) to evaluate anti-fouling and anti-thrombotic effects. 1HNMR and FT-IR 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 compared to those of pristine PVC surface. |
