NOVELTY - The preparation method of graphene oxide/poly(ether benzimidazole) composite material involves dispersing graphene oxide in dimethyl sulfoxide to form organic solution of graphene oxide, reacting 3,3'-diaminobiphenyl, 4,4'-dibenzoic acid ether and poly(methyl methacrylate) at 140-160 degrees C for 1-3 hours under nitrogen atmosphere, and washing to obtain poly(ether benzimidazole), and dissolving poly(ether benzimidazole) in organic solution of graphene oxide and evaporating solvent. The method is solvent exchange method. USE - Preparation of graphene oxide/poly(ether benzimidazole) composite material (claimed). ADVANTAGE - The method enables simple preparation of graphene oxide/poly(ether benzimidazole) composite material with excellent mechanical properties and thermal stability.
