Disclosed is a carbon dioxide absorbent and a carbon dioxide separation method using the same that greatly reduces energy consumption due to a small amount of latent heat required in regeneration of absorbents, enhances COabsorption rate, undergoes almost no thermal denaturation even at high temperatures while absorbing carbon dioxide, and results in a considerable reduction of the cost associated with absorption of carbon dioxide.

Carbon dioxide absorbent and method for separating out carbon dioxide by using same

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 as a solvent to prepare a mixture solution; and drying the mixture solution to remove the solvent from 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][BF]).
