摘　　要：聚醚砜(PES)超滤膜的疏水性导致在处理水的过程中驱动力高、易污染,需要亲水化改性.调研了PES超滤膜的亲水化改性方法:物理共混、化学共聚、表面物理吸附、表面化学处理、表面接枝等.围绕亲水化综述了PES超滤膜亲水改性的研究进展.The hydrophobicity of polyethersulfone(PES) ultrafiltration membranes often causes higher driving force and fouling tendency in water treatment.This presents the necessity in hydrophilic modification of PES Ultrafiltration membranes. The progresses in modification of PES ultrafiltration membranes were reviewed. The modification methods including blending, copolymerization, surface absorption, chemical treatment of the surface and grafting polymerization on the surface were discussed.
