IONIC LIQUID-POLYMER GEL MEMBRANE WITH IMPROVED GAS PERMEABILITY, AND PREPARATION METHOD THEREOF |
摘要 |
The present invention relates to an ionic liquid-polymer gel membrane with improved gas permeability, and a preparation method thereof, and more specifically, to a membrane prepared to allow an ionic liquid to be dispersed in a polymer gel, thereby improving gas permeability. Particularly, the present invention relates to an ionic liquid-polymer gel membrane wherein membrane selectivity and permeability exceed an upper bound by increasing the amount of dispersed ionic liquid, and a preparation method thereof. The preparation method of the membrane for separating a specific gas from a mixture gas according to the present invention comprises the following steps of: mixing a polymer, an ionic liquid and PC of a solvent to prepare a mixture solution; and drying the mixture solution to remove the solvent of the mixture solution. In addition, the polymer is polyvinylidene fluoride-hexafluoropropyl copolymer (PVdF-HFP), and the ionic liquid is 1-ethyl-3-methylimidazolium tetrafluoroborate ([emim][BF4]).
