| 摘 要： | 聚氧化乙烯poly(ethylene oxide),PEO]类膜材料含有大量与CO2有很强相互作用的醚氧基团,使得它具有很高的CO2/light gases(例如:H2、N2、CH4)溶解选择性,因此带来很高的CO2/light gases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/light gases选择性大小基本相同,而它们的CO2透气性随着膜材料链段结构的不同而有较大不同.

| Abstract: | 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 h... |
