However, the poor compatibility between polymeric matrix and inorganic filler in MMMs could lead to the generation of interfacial defects resulting in reduced gas selectivity. In this work, with the aim of studying the effect of particle size and pore structure of the filler on the performance of the resultant MMMs, nano/micro sized spherical mesoporous silicas with 2D/3D pore structure (MCM-41 and MCM-48) were synthesized and selected as fillers for the preparation of polydimethylsiloxane (PDMS)-based MMMs. The separation properties of the membranes prepared wRSC advancesEffects of mesoporous silica particle size and pore structure on the performance of polymer-mesoporous silica mixed matrix membranes.PMC90435832021020212032018A0303134412203600321806192KJZD2019144300119lgpy1352173700622076222Ouyang GHao ZZhang ZWang GWang JfalseEffects of mesoporous silica particle size and pore structure on the performance of polymer-mesoporous silica mixed matrix membranes.The fabrication of mixed matrix membranes (MMMs) has been regarded as an effective and economic approach to enhance the gas permeability and selectivity properties of conventional polymeric membranes for gas separation applications.
