Research advances of organic framework membranes in gas separation

Materials with high permeability, high selectivity and high stability are the critical factors to efficient membrane separation processes. Organic framework membranes (OFMs) hold great prospects in gas separation, owing to their high porosity, long-range regular structure, facilely-tailored functionality, and high stability. This review summarized the chemical compositions, structures, fabrications of OFMs and their applications in carbon dioxide capture and separation, olefin/paraffin separation and noble gas separation. Finally, the major challenges and brief perspectives of OFMs in gas separation are tentatively identified.
