摘要
本文以硅橡胶和聚酰亚胺为基础,从高分子的化学组成、分子链段的运动能力、侧基的大小及其作用等几个方面,讨论了聚合物的化学结构对其均质膜的气体选择透过性能的影响,以溶解扩散过程对气体分离膜材料的透气行为进行了剖析,井简述高分子化学结构对其成膜时结晶情况的影响及对气体透过的作用;还概述了气体分离膜科学发展的历史以及基本原理.
The data of silicon rubber and polyimide permselectivity and divide gas penetratic processes into two programs: Diffusion and Solubility, this paper discussed about chemical structure's influence on permselectivity in polymeric gas separation membrane, such factors as chemical comprise; polymer backbone mobility; bukyl functional group and polymer crystalinazition. More over, it reviewed the history of polymeric gas separation membrane and development of foundmental theory.
