| 研究実績の概要 |
In this project, we developed a series of polymer-silica hybrid materials/membranes with interpenetrating dual-network structure. The amine-containing hydrophilic polymers were selected to form the first flexible network while bridged type, hydrophilic organosilica precursors were adopted to form the second rigid network. Effects of polymer type, organosilica source, and catalysis species on the formation of dual-mode hybrid network structure regarding structure stability, microphase separation, and gas separation properties were systematically studied. 1,2- bis(triethoxysilyl)ethane (BTESE) and polyethylenimine (PEI) were found to be very suitable to fabricate robust dual-network structure for CO2 separation with excellent molecular sieving effect.
