High-performance gas separation using mixed-matrix composite membranes containing graphene nanoplatelets

Mixed-matrix composite membrane (MMCM) made from a dense selective layer filled with various filler on the top of a porous support layer is an effective method to obtain high gas separation performance compared to the conventional mixed-matrix membrane. In this study, the high CO2-selective Pebax-1657 layer was coated onto the porous PES support layer with desirable mechanical stability, and then graphene nanoplatelets (GNPs) were embedded into...
