摘要:

纳滤膜对水中污染物的分离截留性能优异,膜污染控制和抗污染强化是该技术发展的研究热点。纳滤膜改性是强化纳滤膜抗污染性能的方法之一,基于两性离子材料的改性纳滤膜凭借两性离子材料静电作用与水分子结合的特性,在渗透性和抗污性方面表现优秀。系统综述了强化抗污染的两性离子纳滤膜的改性方法,包括涂覆法、接枝法、界面聚合法、自组装和共混掺杂法等,并阐释了各方法所制备纳滤膜的抗污效能和适用条件,最后对各改性方法做出了展望,以期为两性离子材料在纳滤膜改性和实际应用中的研究提供参考。

Abstract:

Nanofiltration membrane has excellent performance of separating and retaining pollutants in water. The nanofiltration membrane fouling control and anti-fouling enhancement are research focuses of its development. The modification of nanofiltration membrane is one of the methods to enhance the anti-fouling property of nanofiltration membrane. The modified nanofiltration membrane based on zwitterion materials has stronger permeability and anti-fouling by virtue of the characteristics of zwitterionic material’s electrostatic interaction and the combination with water. The modification methods of zwitterion nanofiltration membranes with enhanced anti-fouling including coating,grafting,interfacial polymerization,self-assembly and blending doping were systematically reviewed. The anti-fouling efficiency and applicable conditions of each modification method were illustrated. Finally,the modification methods based on zwitterion nanofiltration membranes were prospected. It was hoped to provide reference for the modification and practical application of zwitterionic materials in nanofiltration membranes.

Key words: nanofiltration membrane, modification, zwitterion, membrane fouling
