中文摘要：
聚氧化乙烯[poly（ethylene oxide），PEO]类膜材料含有大量与C02有很强相互作用的醚氧基团，使得它具有很高的CO2／lightgases（例如：H2、N2、CH4）溶解选择性，因此带来很高的CO2／lightgases选择性．介绍了具有高溶解选择性CO2气体分离膜材料的筛选，重点叙述了PEO类膜材料的发展以及目前主要的PEO类膜材料的气体分离性能．当PEO含量达到足够高时，PEO类膜材料的CO2／lightgases选择性大小基本相同，而它们的CO2透气性随着隧耕抖铭好圣圭桷的泵同而右翁女不同
英文摘要：
Membrane materials of poly（ethylene oxide） （PEO） containing numbers of ether oxygen groups, which has favorable interaction with CO2, has high solubility selectivity of CO2/light gases resulting in high selectivity of CO2/light gases. The screenings of membrane materials with high solubility selectivity for separating CO2 was introduced. The development and gas separation properties of main PEO membrane materials were described emphatically. When the content of PEO reaches high enough, the PEO membrane materials have the almost closer solubility selectivity of CO2/light gases and different CO2 permeability he cause of the different chain structures of these membrane materials.
