Abstract
Mixed matrix membranes (MMMs) have attracted remarkable attention as a leading-edge membrane filtration technology, due to their unique properties combining inherent characteristic of polymer and inorganic filler. Metal organic frameworks (MOFs) is one of recent nanoporous materials that has favorable to be used as a filler in MMMs to enhance molecular separation performance. This article aims to review the synthesis, properties, and performance of polymer/MOFs based MMMs. Literature search was conducted through Sciencedirect and Google Scholar by using the keywords of metal organic framework, MMMs, polymers, filler, and membrane filtration. The polymer/MOFs based MMMs can be synthesized using the in situ, layer by layer, and post-synthesis modification methods. Polymer/MOFs based MMMs have porosity of 57 to 65%, contact angle of 46.02 to 75.27, thickness of 0.34 to 0.5 mm, tensile strength of 2.33 to 3.34 MPa. Polymer/MOFs based MMMs also demonstrated superior performance in term of water permeability and BSA/salt rejection. The water flux of the MMMs reached up to 35.39 L/m2. h., and the rejection of MMMs toward BSA salt ions were up to 85% and 60%, respectively. The Polimer/MOFs based MMMs has great potential for ultrafiltration and nanofiltration.
