| 摘 要： | 系统概述了相转化法制备聚矾膜时聚矾含量、添加剂、凝固浴及铸膜液在空气中的蒸发时间对其结构和性能的影响。随着聚矾含量的增加，膜结构从疏松向致密转变;在铸膜液中添加适合的添加剂可制备适当结构和渗透性能的聚矾膜;在凝固浴中添加适量的溶剂，可有效抑制膜内大孔结构的形成;空气中蒸发时间的增大时，膜表面趋于疏松，当增加到一定程度后基本趋于稳定。还综述了相转化法制备聚矾膜时聚矾含量、添加剂、凝固浴及铸膜液在空气中的蒸发时间对其结构和性能的影响。

| Abstract: | The effects of the composition of the polymer, additives，the solvent evaporation time,and the gelation media on the membrane structures/morphology which are prepared by phaseinversion process will he represented in the paper. The structure of membranes become thick shinlayer from thin skin layer with increase in the composition of the polymer. The appropriate structure and permeability of membranes can he prepared by using additives in the casting solution.The macropore structure will he suppressed by adding solvent in the gelation media. The structure of top surface become the loose structure with increase in the solvent evaporation time, and it will he a certain degree after a specific value of the solvent evaporation time.The effects of the composition of the polymer，additives，the solvent evaporation time，and the gelation media on the membrane structures/morphology which are prepared by phase inversion process. |
