Poly(vinylidene fluoride)-based cationic polymers and their antibacterial film application |
| 초록 |
Vinylidene fluoride (VDF) based polymers attract tremendous attention due to exceptional properties such as weatherability, chemical inertness, and good mechanical properties. However, their lack of antibacterial property limits their adoption as biomedical materials. In this study, to overcome this problem, PVDF-based cationic polymers were prepared by grafting quaternized ammonium or pyridinium monomers. The polymers could kill gram-positive gram-negative, and the pathogenic yeast (antimicrobial activities ＞ 99.99%). By blending with commercial PVDF, 1 wt% or 5 wt% of the polymers were added to the pristine PVDF to provide PVDF films with antimicrobial properties. The blend films show notably higher antimicrobial performances (＞99% for Blend-Q4VP-5) as well as enhanced mechanical properties compared to those of pristine PVDF. |
