The transport of carbon dioxide and methane in a poly(vinylidene fluoride-cohexafluoropropylene) polymeric membrane containing ionic liquid was studied. Two ionic liquids 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([hmim][TF2N]) and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([emim][TFSI]) were used for preparation of ionic liquid membranes. Gas permeation measurements of pure gases were conducted using a semi-open cell which is divided into two parts by the membrane sample. Constant pressure P1 (2 bar) was maintained at the feed side, while vacuum was set at the permeate side in the beginning of an experiment. Increase of permeate pressure P2 with time was recorded and the gas flux and permeability were evaluated.
