▎ 摘　　要

NOVELTY - Preparation of nanocomposite anion-exchange membrane involves mixing positively-charged brominated polyphenylene ether and graphene oxide solution, obtaining casting solution and casting. The positively-charged brominated polyphenylene ether is obtained by dissolving brominated polyphenylene ether in solvent (a), adding alkali functional reagent and reacting. The graphene oxide solution is obtained by dissolving graphene oxide in solvent (b) and reacting. USE - Preparation of nanocomposite anion-exchange membrane (claimed). ADVANTAGE - The method provides nanocomposite anion-exchange membrane with high productivity, by economical and simple process. The graphene oxide used in the method has high specific surface area and strength, and improves mechanical property and conductivity of the anion-exchange membrane.
