摘　　要：膜分离过程被普遍存在的膜污染问题所困扰。两性离子聚合物是在同一分子中含有阴离子和阳离子单元的代表性材料,由于其超亲水性、化学稳定性和优异的防污能力,在生物医学和分离材料等领域受到了广泛关注。将两性离子分类,综述了将两性离子材料结合到膜表面以提高膜抗污染性能的常见方法,包括引发剂引发、等离子体引发、紫外诱导引发等。最后对两性离子改性高分子膜未来的发展进行了简单的评价和展望。Membrane fouling is a common problem in membrane separation.Zwitterionic polymers are representative materials containing anions and cationic units in the same molecule.Due to their super-hydrophilicity,chemical stability and excellent antifouling ability,it has received extensive attention in the fields of biomedicine and separation materials.In this paper,zwitterions were classified and the common methods to improve the anti-fouling performance of membrane by binding zwitterions to membrane surface are reviewed,including initiator initiation,plasma initiation and UV-induced initiation.Finally,the development of amphoteric ion modified polymer membrane was simply evaluated and prospected.
