| Outline of Final Research Achievements |
Silsesquioxane (SQ) has demonstrated properties that are seen in both silica (SiO2, inorganic) and silicone (organic). Conventionally, SQ-derived sols are coated onto ceramic supports, followed by firing at 200~400C, which facilitates further condensation to form a SQ separation layer with high separation performance. In this work, we proposed, for the first time, the strategy for fabricating silsesquioxane (SQ) membranes at low temperature using photo-induced sol-gel processing. Radical and cationic polymerization of SQ membranes showed high degrees of separation factor and permeance for water/isopropanol separation in pervaporation.
