Tuning the nanopore structure and separation behavior of hybrid organosilica membranes
2014
Microporous and Mesoporous Materials
The exceptional hydrothermal-and solvent stability of organically linked silica makes it a promising candidate material for molecular separation membranes. Tailoring towards specific separation properties however requires precise control over the pore structure. Here we show that this can be achieved by adjusting the acid-to-Si ratio immediately before the onset of physical drying of the 1,2-bis(triethoxysilyl)ethane-based polymeric colloidal sols. This procedure provides uniform coating
