聚偏氟乙烯多孔膜的改性研究进展

Research progress of modification of poly(vinylidene fluoride) porous membrane

为了提高聚偏氟乙烯 ( PVDF)多孔膜的抗污染性 ,必须设法改善其表面亲水性 .本文从物理改性、化学改性、低温等离子、辐照改性和光化学改性 5个方面详细介绍了各种方法 。

In order to increase the antipollution of PVDF porous membrane,we have to improve its surface hydrophilicity.This paper introduces in detail each method and its results from the modification of physics,chemistry,low temperature plasma,irradiation and photochemistry.
