摘要
自具微孔高分子(polymers of intrinsic microporosity,PIMs)是近年来出现的一种新型有机微孔材料,由含有扭曲结构的刚性单体聚合而成,具有比表面积高、化学和物理性质稳定、微孔结构可控等优点,在均相催化、氢气储存等方面表现出巨大的应用潜力。因其优越的气体分离性能,PIMs气体分离膜更是吸引了众多研究者的关注,发展迅速。本文总结了PIMs的分类及其在气体分离膜中的应用,重点介绍了PIMs气体分离膜的结构调控与改性方面的研究进展,分析了PIMs的分子结构与气体分离性能间的内在关联,最后提出了目前研究中存在的一些问题并对其发展做出了简要的评述。
Polymers of intrinsic microporosity （PIMs）, as novel microporous organic polymers polymenzed oy rigid monomers that have sites of contortion, have great application potential in homogeneous catalysis and hydrogen storage due to their high specific surface, chemical and physical stability and pore size controllability. Particularly, PIMs composed of polymer chains attract more attention in gas separation membranes due to their superior gas separation properties and good solubility. Here, the classification and applications of PIMs as well as the properties including stability, gas permeability and gas selectivity of PIMs gas membrane are introduced. The structure controls and modifications of PIMs gas membrane and the relationship between molecular structures and gas separation properties are described in detail. Finally, the problems existed in the present research are pointed out and a brief comment on the development is given.
