NOVELTY - Preparation of poly-1,5-diamino anthraquinone-modified graphene nanocomposite material comprises dissolving protonic acid in N,N-dimethylformamide solution to obtain acid solution, dividing into two parts, adding one part with 1,5-diamino anthraquinone monomer and graphite oxide, and dispersing to obtain first sol solution; and dissolving oxidant in remaining acid solution, and dropping first sol solution; placing into insulator, washing with deionized water, adding to aqueous reducing solution, washing precipitate with deionized water, and centrifuging to obtain powder; and drying. USE - Method for preparation of poly-1,5-diamino anthraquinone-modified graphene nanocomposite material (claimed) used for secondary battery, supercapacitor, microwave absorbing coating, and sensors. ADVANTAGE - The method is simple and has low cost. DETAILED DESCRIPTION - Preparation of 1,5-diamino anthraquinone-modified graphene nanocomposite material comprises: (A) dissolving protonic acid in N,N-dimethylformamide solution to obtain acid, dividing into two parts, adding one part with 1,5-diamino anthraquinone monomer and graphite oxide, ultrasonically dispersing to obtain purple-brown first sol solution; and dissolving oxidant in another part of acid solution, and slowly dropping first sol solution to obtain mixed sol; (B) placing into constant temperature insulator, and reacting to obtain poly-1,5-diamino anthraquinone-modified graphene oxide composite powder intermediate product; (C) washing with deionized water to neutralize, adding to aqueous reducing solution while stirring, washing precipitate with deionized water, and centrifuging to obtain powder; and (D) drying to 50-70 degrees C in oven.
