Description	Ionic liquid polymer gel membranes based on poly(vinylidene fluoride-co-hexafluoropropylene) (p(VDF-HFP)) were prepared by solvent casting from a solution in acetone. The membranes contain from 20 wt% to 80 wt% of pure or mixed ionic liquids based on the imidazolium cation: 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMIM][TFSI]) and 1-hexadecyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([HdMIM][TFSI]). Both ionic liquids have the fluorinated anion bis(trifluoromethylsulfonyl)imide, which should make them more compatible with a fluoropolymer matrix, while the different tail lengths in the cation give significantly different melting points. The thermal and mechanical properties of the blend membranes were evaluated and compared with the neat polymer. The performance of the membranes was tested in terms of pure gas permeability and selectivity, separation of limonene/carvone mixtures by pervaporation, and influence of a low water content in the feed on separation by the blended membrane Ionic liquid polymer gel membranes based on poly(vinylidene fluoride-co-hexafluoropropylene) (p(VDF-HFP)) were prepared by solvent casting from a solution in acetone.
