摘要(Abstract)：

为提高聚氯乙烯（PVC）的亲水性和抗污染性能，分别将聚乙二醇（PEG 20000）、聚（氯乙烯-co-甲基丙烯酸二甲氨基乙酯）（PVD）和磺化聚砜（SPSf）引入PVC基质中，非溶剂致相转化法（NIPS）制备出电中性PVC/PEG（M1）、荷正电PVC/PVD（M2）和荷负电PVC/SPSf（M3）3种共混超滤膜。并研究3种膜的表面化学组成、结构形貌、孔径和孔隙率、水接触角、荷电性、渗透性、牛血清蛋白（BSA）截留及抗污染性能。结果表明：M1、M2和M3均是具有海绵结构的超滤膜，孔隙率、水接触角和纯水通量均表现为M1 > M3 > M2。对BSA的截留率为M3（99.3%） > M2（90.6%） > M1（86.2%），通量恢复率为M3（98.2%） > M1（90.1%） > M2（73.0%），荷负电的M3具有更优异的持久抗污染能力。
