Review of Recent Researches on the Application of Metal-Organic Framework /Polymer Mixed Matrix Membranes for Gas Separation

Gas separation by polymer-based membranes, has many applications in various fields particularly gas refinery, petrochemical industries and environmental protection. With the growing interests in this technology, a new type of membranes as mixed matrix membranes (MMMs) have been fabricated in order for employing the advantages of both polymeric and inorganic materials, simultaneously. The metal-organic frameworks (MOFs) incorporated in polymer matrix indicated a desirable gas separation performance. In the present study, first, the structure of MOFs, their role in the membrane and gas transfer mechanism is studied. Then, the recent studies on MOFs/polymer MMMs and the effects of factors on their gas separation performance are reviewed.
