摘　　要：考察了溶剂处理对聚砜非对称中空纤维膜气体分离性能的影响．利用溶剂在膜表面缺陷孔中溶胀聚砜的作用，调整膜表面孔分布，降低表面孔隙率。The effects of solvent post treatment on separation properties of PSF (polysulfone) hollow fiber membrane were examined. Not only adjusting surface pore distribution but also reducing surface porosity were as a result of PSF resolution and swelling in surface defect pores. The study has given a method of increasing gas selectivity by solvent treatment.
