干湿法纺制聚砜中空纤维N2－H2分离膜（Ⅱ）凝胶条件的影响

Dry wet spinning of PSF hollow fiber membranes for the separation of N 2-H 2(Ⅱ) effects of coagulation conditions

研究了采用干湿法工艺纺制中空纤维膜时凝胶条件对膜性能及结构的影响，着重研究了使用不同的有机溶剂作为芯液时对膜性能及成膜过程的影响。

Effects of coagulation conditions on the membrane permeation properties and membrane structures were studied, especially that of bore liquid. The structures of membranes were observed by SEM and discussed by phase inversion theory and solubility parameter theory.
