摘要： 研究了带有不同烷基取代基的Cardo聚芳醚酮均质膜对H2、O2、N2、CO2和CH4气体的透气性能,讨论了气体透过对温度的依赖性。与未改性酚酞聚芳醚酮相比,在主链苯环上引入异丙基侧基会使气体透过系数提高3～6倍；每个结构单元苯环被4个甲基取代后,气体透过系数和选择分离系数同时得到较大改善,其中H2的透过系数为22 barrer,H2/N2分离系数为114.

Abstract: The gas permeation properties of a series of cardo polyaryletherketone materials are reported.In this series,hydrogen atoms of benzene rings on the backbone are systematically replaced with different alkyl substituents.The effects of temperature and structure variation on gas permeability and selectivity are discussed in detail.The experimental results revealed that the polyetherketone obtained by the introduction of dimethyl and diisopropyl substituents to phenolphthalein unit is 3～6 times more permeable than the unmodified one for the gases studied.
