摘要：

Alkali-treated poly(vinylidene flouride) (PVDF) grafted poly(N-isopropylacrylamide) (PNIPAAm) copolymer (PVDF-g-PNIPAAm) was synthesized via radical copolymerization and the different grafting ratio of PNIPAAm was obtained by regulating reaction time. The copolymer membranes were prepared by phase inversion method. The results indicated that the grafting ratio of PNIPAAm was enhanced with the increase of reaction time resulting in the formation of microporous structures on the membrane surface due to the pore-forming ability of the amphiphilic structure. In addition, the hydrophilicity and temperature-sensitivity were also improved with the increase of grafting ratio. At the room temperature, the copolymer membrane exhibited excellent protein-resistant property due to the hydrophilicty of PNIPAAm.
