Cyclic olefin copolymer (COC)-metal organic framework (MOF) mixed matrix membranes (MMMs) for H2/CO2 separation

In this study, thermoplastic based mixed matrix membranes (MMMs) were prepared by using cyclic olefin copolymer (COC) and two different metal organic frameworks (MOFs), HKUST-1 and MIL-53(Al) via solution mixing (SM) and melt processing (MP) methods. Structural and physical properties of COC, MOFs, and MMMs were characterized by SEM, XRD, TGA, and DMA methods. H2 and CO2 permeability values of MMMs were measured and ideal selectivity values (α)...
