Emission of Greenhouse gases is a major concern these days. A number of techniques are used for separation of CO2, methane and other hydrocarbons but mixed matrix membrane based separation is gaining significant importance day by day. A number of different polymers have been employed for the fabrication of mixed matrix membranes for example cellulose acetate, polyimides, polysulfone, pebax, polybenzimidazole, polymer of intrinsic porosity, polyurethane, chitosan and many more. Likewise, along with other fillers, Metal organic frame works have also been tested as additive for the mixed matrix membranes as they offer several advantages over other fillers. This review majorly presents use of three polymers viz. cellulose acetate, polyimides and polysulfone, for fabrication of mixed matrix membranes. All of these polymers are of utmost industrial importance in the field of separation. Further use of different other polymers in this field is also discussed shortly.
