POLYBENZIMIDAZOLE COPOLYMER CONTAINING ARYLENE ETHER GROUP AND ELECTROLYTE MEMBRANE COMPRISING THE SAME

摘要

A polybenzimidazole copolymer is provided to increase the solubility to an organic solvent by reducing the crystalline and to ensure high hydrogen ion conductivity while maintaining thermal stability. A polybenzimidazole copolymer has a structure indicated as the chemical formula 1, In the chemical formula 1, Ar and Ar' are independently arylene group; n and m are independently 1-10,000; and the rate of n and m is 9~1:1~9.
