USE - The method is useful in preparing N-substituted polyaniline acid covalently grafted graphene composites material (claimed). The material is useful in super-capacitor, sensor and solar energy battery. DETAILED DESCRIPTION - Preparing N-substituted polyaniline acid covalently grafted graphene composites material, is new. The method uses amino diphenylamine of graphene oxide functionality and base point N to the rear in reduction-carboxylic acid substituted polyaniline covalently grafted on reduced graphite oxide. The method comprises (i) preparing graphite powder by hummer method and subjecting to ultrasonic dispersing to obtain homogeneous solution, (ii) taking p-aminodiphenylamine proton acid solution of a certain volume and anhydrous ethyl alcohol solution, mixing and subjecting to ultrasonic dispersing, (iii) placing under ice water bath, taking sodium nitrate solution, slowly dropping and mixing solution, adding graphite oxide, slowly dropping, reacting, hydrating hydrazine and reducing ammonia water, and (iv) taking N RGO and quantifying phenyl glycine, dissolving in protonic acid solution, fixing middle concentration and dispersing ultrasonically, adding initiator in ammonium sulfate, reacting once and processing.
