Abstract
New ionic liquid-solid-polymer mixed matrix membranes were proposed for gas separations such as COremoval from natural gas or N. For the new mixed matrix membranes, the solids such as carbon molecular sieves, microporous molecular sieves, MCM-41 type of mesoporous molecular sieves, or polymer of intrinsic microporosity (PIM) are coated (or impregnated) with ionic liquids such as 1-butyl-3-methyl imidazolium bis[trifluoromethylsulfonyl]amide. The ionic liquids coated or impregnated solids are then dispersed in the continuous polymer matrix to form mixed matrix membranes. These hybrid mixed matrix membranes will combine the properties of the continuous polymer phase, the ionic liquids, and the dispersed ionic liquids coated or impregnated solids phase, which will possibly open up new opportunities for gas separation processes such as COseparation from natural gas or flue gas.
