Varying concentration of ionic liquid were incorporated in the dope solution and flat sheet dense membranes were casted by dry phase inversion method. The morphology of the membranes was observed by Field Emission Scanning Electron Microscope (FESEM). The gas permeation experiments were run at room temperature and 2 bar pressure. The membranes showed a dense structure with no pore formation indicating the compatibility of polymer and ionic liquid. CO2 Gas permeability of synthesized polymer/IL membrane was significantly increased by blending ionic liquid in polymer matrix due to high solubility of CO2 in EMIMTf2N ionic liquid. These membranes can be considered as a potential material for bulk removal of CO2 from flue gases and natural gas. © 2016 Published by Elsevier Ltd. %O cited By 15; Conference of 4th International Conference on Process Engineering and Advanced Materials, ICPEAM 2016 ; Conference Date: 15 August 2016 Through 17 August 2016; Conference Code:131138 %L scholars7408 %J Procedia Engineering %D 2016 %R 10.1016/j.proeng.2016.06.477
