Ionic liquid polymer gel membranes based on 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]).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 small water content in the feed on separation by the blended membrane.
