چکیده مقاله :
Global CO2 emissions have increased steadily due to use of fossil fuels and industrial applications. Therefore, it is necessary to decrease of energy consumption and CO2 concentration by CO2 separation from natural gas. There are different technologies to CO2 separation. CO2 separation membranes prepared by green, simple, and efficient methods have faced great challenges. In recent years, Polymer based membrane materials be applied in vast variety of the membrane materials. Polymeric membrane materials show high permeability to CO2. But having excellent selectivity should be considering preparing polymeric membranes. This review summarizes advances in polymeric materials having very high CO2 permeability and excellent CO2/N2 selectivity that enhance the performance of polymeric membranes. Five important classes of polymer membrane materials are highlighted: polyimides, thermally rearranged polymers (TRs), substituted polyacetylenes, polymers with intrinsic microporosity (PIM) and poly (ethylene oxide) (PEO) that are high performance to CO2 separation.
