EFFECT OF FUNCTIONALIZATION OF METAL ORGANIC FRAMEWORK (MOF) AND METAL ORGANIC POLYHEDRA (MOP) MATERIALS IN POLYIMIDES FOR GAS SEPARATIONS AT HIGH PRESSURE AND HIGH TEMPERATURE

摘要

Energy related gas separations, such as H2 from CO2 in thenwater-gas shift reaction and N2 from CO2 in the generation ofnelectricity, are industrial processes where membranes can benemployed. In these separations, the mechanical, thermal, andnchemical stability of the membranes are important requirements forntheir separation performance. Recently, mixed-matrix membranesn(MMMs) containing porous metal-organic frameworks (MOFs) havenbeen tested for gas separations with promising results [1-3]. In thesenstudies, significant enhancement of gas permeability and improvednparticle dispersion were observed. Although MOFs disperse well innpolymer matrices, aggregation of the nanoparticles is still evident.nSince the linkers in metal-organic hybrid materials (i.e., MOFs, ZIFs,nand MOPs) can be functionalized, their pore architecture and affinitynfor gases and polymers can therefore be tuned.
