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
