摘要:

混合基质膜(MMMs)是结合了无机填料和有机基质特点的一类膜材料,因其在气体分离应用上具有良好的渗透通量和分离性能被广泛关注。无机填料诸如二氧化硅纳米颗粒球、沸石分子筛、金属有机框架(MOF)、氧化石墨烯(GO)、碳纳米管(CNT)均被广泛应用于混合基质膜的制备,但是碍于无机填料在有机相中的分散性问题、两相相容性问题和界面缺陷问题,常会导致较差的气体分离性能。针对近年通过对无机填料进行表面官能化修饰、共价交联、多元填充、调控形貌等来改善混合基质膜气体分离性能的研究进行总结和阐述,并对其未来的发展趋势进行了展望。

Abstract:

Mixed matrix membranes(MMMs) is a kind of membrane material of combining the characteristics of inorganic fillers and organic matrices has been widely concerned because of its good permeability and separation performance.The inor-ganic fillers,such as SiO2 nanoparticle spheres,zeolite molecular sieves,metal-organic framework (MOF),graphene oxide (GO)and carbon nanotubes(CNT) are all widely applied in the preparation of MMMs,but issues of poor dispersion,poor compati-bility and existence of interface defects often lead to poor gas separation performance.The factors that improve the gas separa-tion performance of MMMs through surface functional modification,covalent cross-linking,multiple fillers and size and mor-phology controlling in recent years were summarized and decomposed.The development trend of MMMs in the future was also prospected.

Key words: gas separation, mixed matrix membrane, interface design
