BLEND MEMBRANES BASED ON POLYBENZIMIDAZOLE (PBI) AND POLYMERIC IONIC LIQUIDS (PILS) AND A PROCESS FOR THE PREPARATION THEREOF

摘要

The present invention discloses blend membranes based on polybenzimidazole (PBI) and polymeric ionic liquids (PILs), wherein said PBI and aliphatic PIL blend enhances H+ and OH- ions conductivity. In particular, the invention discloses a blend membrane comprising of polybenzimidazole (PBI) and poly (diallyl dimethyl ammonium) trifluoromethane sulphonate with enhanced proton and hydroxyl ion conductivity.
