NOVELTY - Double-grafted heterocyclic azobenzene graphene energy storage material (I) comprises two azobenzene molecules, 2-aminothiazole azobenzene, 3,5'-di hydroxylaminoazobenzene is grafted onto the surface of graphene in the form of covalent bonds. The graphene is grafted with two azobenzene molecules, the sulfur atoms, nitrogen atoms and hydroxyl groups of the two azobenzene molecules interact with each other to form final product. USE - Double-grafted heterocyclic azobenzene graphene energy storage material. ADVANTAGE - The double-grafted heterocyclic azobenzene graphene energy storage material has very high energy density up to 145 Wh/kg, improves isomerization rate up to 90%, monomermolecule ratio upto 30%, improves half-life and has great application prospect. DETAILED DESCRIPTION - Double-grafted heterocyclic azobenzene graphene energy storage material of formula (I) comprises two azobenzene molecules, 2-aminothiazole azobenzene, 3,5'-di hydroxylaminoazobenzene is grafted onto the surface of graphene in the form of covalent bonds. The graphene is grafted with two azobenzene molecules, the sulfur atoms, nitrogen atoms and hydroxyl groups of the two azobenzene molecules interact with each other to form final product.. An INDEPENDENT CLAIM is included for a method for preparing a double-grafted heterocyclic azobenzene graphene energy storage material, which involves: (A) dispersing 2-aminothiazole azobenzene, 3,5'-dihydroxyaminoazobenzene, sodium hydroxide and Sodium nitrate in deionized water and adding hydrochloric acid, and carrying out reaction under ice bath; and (B) dispersing aqueous solution and reducing graphene oxide to react under an ice bath condition, continuing reaction at room temperature of 20-25 degrees C to obtain 2-aminothiazoleazobenzene and 3,5'-dihydroxyamino couple nitrobenzene grafted onto the graphene surface.
