In this work, we report the synthesis and application of novel polymeric membranes, based on polymerized ionic liquids (PILs), to be used for the separation of hydrogen from gas mixtures with CO2. Dense membranes have been developed by using phosphonium-based PILs copolymerised within an original acrylate formulation that allowed to overcome some of the main limitations related to ionic liquid membranes. The membranes showed remarkable separation properties exceeding the Robeson upper bound for the CO2/H2 gas pair.

Abstract
In this work, we report the synthesis and application of novel polymeric membranes, based on polymerized ionic liquids (PILs), to be used for the separation of hydrogen from gas mixtures with CO2. Dense membranes have been developed by using phosphonium-based PILs copolymerised within an original acrylate formulation that allowed to overcome some of the main limitations related to ionic liquid membranes. The membranes showed remarkable separation properties exceeding the Robeson upper bound for the CO2/H2 gas pair.File in questo prodotto:
