CO2 capture technologies have been highlighted over the past decades because of global warming. Among the various technologies for CO2 capture, facilitated CO2 transport membranes show high CO2 selective performance by introducing carrier which interacts with CO2. In this presentation, we prepared and investigated facilitated CO2 transport membrane comprising potassium bis[(trifluoromethyl)sulfonylimide] (TF2N) dissolved in a polymer matrix of Pebax1657. Adding potassium salt to the membrane shows further improvement in gas permeabilities while maintaining or even improving the gas selectivity, compared to the corresponding neat polymer membrane. Therefore, we have demonstrated that KTF2N can act as dual carrier for CO2 and its facilitated transport membrane could be very effective in enhancing the CO2 separation performance.
