Mixed matrix membranes comprising glassy polymers and dispersed mesoporous silica spheres for gas separation

Mixed matrix membranes (MMMs) composed of polyimide Matrimid® and mesoporous silica spheres (MSSs) are prepared, characterized and tested in gas separation of equimolar mixtures H2/CH4 and CO2/N2 at different temperatures. Their performance is compared with MMMs using other glassy polymer: polysulfo...
