摘要
本文叙述了近年来聚酰亚胺气体分离膜的发展概况。讨论了聚合物结构、共聚改性、交联改性和成膜历史对聚酰亚胺透气性能的影响。脂环族聚酰亚胺和六氟二酐(6FDA)型聚酰亚胺兼具有高透气性和高透气选择性,是一类具有发展前途的气体分离膜材料。
Summary Recent advance of polyimide membrane for gas separation was reviewed. The relationship between the permeability for various gases and the structure of polyimides, the composition of the co-polyimides, crosslinking and the histoory of the membrane has been discussed.
