Polymer membranes such as polyimides, polyethers, thermally rearranged polymers (TRs), polymers with intrinsic microporosity (PIM) are well known for their high permeability and excellent mechanical, chemical, and thermal properties. However, the foremost challenge for these polymeric membrane materials is their enhanced selectivity to CO2 without sacrificing permeability. The selectivity problems would be overcome by ionic liquids (ILs) due to their specific chemical affinities to CO2. This specific characteristic property leads to a considerable attention on RTILs-based sequestrations for CO2 separations. The current research trends based on RTIL polymer membranes, together with our original concept of applying RTIL to various polymeric structures will be presented. |
