| Outline of Research at the Start |
Novel organosilica/polymer interpenetrating networks (IPNs) derived membranes will be designed and developed for high efficiency CO2 separation. The formation of IPNs are expected to combine the superior molecular sieving abilities from amorphous organosilica network and CO2-selective sorption/reaction properties from amine-containing polymer network into their IPNs. In addition, the CO2 induced swelling effect and relatively weak thermal stability seen in most polymers can be well addressed via the construction of IPNs.

| Outline of Final Research Achievements |
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. These studies have been presented in several academic conferences and relative research manuscripts have been published in Industrial & Engineering Chemistry Research.

| Academic Significance and Societal Importance of the Research Achievements |
The construction and development of advanced membranes that can simultaneously demonstrate high permeance and selectivity and robustness, is significantly important for high-performance CO2 separations in potentially industrial applications (e.g. CO2 removal from flue gas).
