聚偏氟乙烯膜的亲水化改性研究进展

Review on Hydrophilic Modification of Poly(vinylidene fluoride) Membranes

强疏水性聚偏氟乙烯(PVDF)膜的亲水化改性是当前分离膜研究的热点之一。从膜本体及膜表面两个角度对PVDF膜的亲水化改性进行了综述,介绍了共混、共聚、化学改性、等离子体处理及接枝改性等多种改性方法的机理、特点及改性效果。

Hydrophilic modification of poly（vinylidene fluoride） membranes is one of the hotspots in merebrane science. In this paper, the mechanisms, characteristics, effects of surface and material modification are reviewed, including blending, copolymerization, surface chemistry treatment, plasma treatment and grafting polymerization.
