摘　　要：从改性材料和方法两方面综述近几年抗污染超滤膜材料改性的研究进展情况.亲水/疏水两性基团如含聚氧乙烯或含聚乙二醇单体、双离子两性分子和聚2-甲基丙烯酸羟乙酯及聚丙烯酰胺等是制备高性能、化学稳定超滤膜的主要改性材料.采用自由基引发聚合、取代或酯化反应、共混、表面涂层或等离子体表面处理等作为改性的主要方法.膜材料改性研究的拓展大大提高了有机超滤膜的抗污染性能,使其应用更加稳定,使用范围更加广泛.The research progress on the antifouling modification of uhrafihration membrane materials in recent years is reviewed. Some monomers with hydrophilic/hydrophobic amphipathic groups such as poly （ethylene oxide） or poly（ethylene glycol）, zwitterion, poly（2-hydroxyethyl methaerylate） and poly（aerylamide） are employed to modify and improve the performance and chemical stability of UF membranes. A variety of methods such as free radical initiated polymerization, substitution or esterification reaction, blending, surface coating, plasma surface treatment are used to the modification. Based upon the studies, the antifouling performance of the organic uhrafiltration membranes has greatly enhanced. It also promotes their wider applications.
