摘要
近年来,两性离子作为一种新型的抗污染材料逐渐受到研究者的重视。两性离子聚合物是指在分子链中同时包含阳离子和阴离子基团的高分子,由于在水溶液中具有较强的水合能力与抑制蛋白质吸附性,两性离子高分子膜具有较好的抗污染性。综述了近年来用于高分子膜改性及提高膜抗污染性的两性离子,总结了两性离子改性高分子膜的研究现状,指出了目前研究存在的问题,并对未来的发展趋势作了展望。
In recent years,as a new type of anti-fouling material,the zwitterion has attracted more and more at-tentions.Zwitterionic polymer contains both cationic and anionic groups in the polymer molecules.The anti-fouling performance of zwitterionic polymer membranes was enhanced obviously due to the strong hydration and protein adhesion resistance in aqueous solution.This article reviews several typical zwitterions for the mem-branes modification and the improvement of anti-fouling performance in recent years.The current research,ex-isting problems and development trends of the membranes modification with zwitterions are also presented.
