聚偏氟乙烯膜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。对PVDF膜近年来在共混改性、表面化学改性、表面接枝改性等方面的研究进行了综述,并针对PVDF分离膜改性领域今后的研究提出建议,指出膜材料共混改性是今后发展的主要方向。.

Hydrophilic modification of poly （vinylidene fluoride） membranes is one of the hot spots in membrane science. The development of methods and the achievement of studies on modified PVDF separation membranes were re- viewed. The methods consisted of blending modification, surface chemical modification and surface grafting modification. A general review of the future research in modified PVDF separation membrane was presented as well. It is evident that the solution blending of membrane materials is the main trend in the modification of PVDF membranes.
