Thin, continuous, mesoporous silica membranes are formed on polymeric hollow fibers via liquid-phase coating at roomtemperature and aging with tetraethylorthosilicate (TEOS) vapor at 100 °C. After liquid extraction of the surfactant template and mesopore infiltration with an aminoalkyloctasilsesquioxane, the membrane displays CO2-selective gas permeation properties.
