摘　　要：介绍了国内外用浸入沉淀相转化法制备聚砜类纳滤膜的研究现状,系统阐述了浸入沉淀相转化法制备聚砜类纳滤膜时,聚合物含量、溶剂、添加剂、凝固浴、预蒸发时间和辐照对其结构和性能的影响,通过对这些因素的调节,可以改变相分离时的热力学和动力学过程,控制膜皮层的厚度、致密性,改变膜截面的孔结构,对膜的水通量和分离性能产生影响。Research status of polysulfone nanofiltration membranes by phase inversion at home and abroad are introduced. The effect of the polymer concentration, solvent, additive, coagulating bath, evaporation time and microwave irradiation on structure and morphology of the membranes which being prepared by phase inversion are analyzed. These factors mainly change process of thermodynamics and kinetics, controlle the membranes morphology, influence the water flux and separation performance of membrane.
