摘　　要：聚氯乙烯(PVC)具有价格低廉、优良的耐酸碱性、耐化学腐蚀性和阻燃性等优点,是一种重要的分离膜材料.针对PVC膜材料在使用过程中容易出现膜污染和渗透效率低等问题,亟需对PVC材料进行改性或重新设计.两亲高分子是同时含有疏水链段和亲水链段的高分子,能同时提供材料力学性能和功能性,能有效实现功能高分子的“结构与功能统一”.PVC材料的两亲化是实现PVC材料功能化和PVC分离膜高性能化的重要手段.本综述主要涉及两亲PVC的制备方法以及两亲PVC分离膜的研究进展.Polyvinyl chloride(PVC)is one of the most important membrane materials,due to its low cost,stiffness,excellent resistance towards acid,base and solvent.However,PVC membrane has some disadvantages,such as the high fouling propensity,low permeability,etc.,thus,modification or even redesign of PVC material are highly desired.Amphiphilic copolymers contain both hydrophobic and hydrophilic segments,which provide the materials with both mechanical strength and functions.Amphiphilic PVC is critical for the functionalization of PVC materials and to fabricate high-performance PVC membranes.This review mainly involves progress in amphiphilic PVC and the structures and properties of amphiphilic PVC based membranes.
