Mesoporous Silica Sphere-Polysulfone Mixed Matrix Membranes for Gas Separation

A series of mixed matrix membranes were prepared comprising polysulfone Udel matrix and ordered mesoporous silica spheres as filler with loadings varying between 0 and 32 wt %. The interaction between the filler and the polymer was studied by scanning and transmission electron microscopy, thermograv...
