▎ 摘　　要

NOVELTY - The method for preparing polybenzimidazole cross-linked film by functionalized graphene oxide, involves adding polybenzimidazole, functionalized graphene oxide and phosphoric acid. The mass of functionalized graphene oxide is 1-25 wt.% of polybenzimidazole. The phosphoric acid doping amount per repeating unit is 1-5. USE - Method for preparing polybenzimidazole cross-linked film by functionalized graphene oxide for high temperature fuel cell and sensors. ADVANTAGE - The method enables preparation of polybenzimidazole cross-linked film with excellent mechanical properties and alcohol resistance.
