NOVELTY - Graphene-modified nitroxide polymer material is obtained by functionalized reduced graphene oxide as an intramolecular dopant modified nitroxide polymer. USE - Graphene-modified nitroxide polymer material. ADVANTAGE - The graphene-modified nitroxide polymer material has excellent conductivity and good application in battery electrode material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene-modified nitroxide polymer material, which involves: (A) adding radical polymer monomer M and functionalized reduced graphene oxide G-Br to the reaction flask under the condition of nitrogen, and adding solvent and the catalyst to the flask, degassing was by three freeze-thaw cycles, then adding copper(I) bromide under nitrogen, and sonicating flask for 30 minutes, adding initiator, and reacting mixture for 8 hours under nitrogen protection at a reaction temperature of 70 degrees C, and cooling flask in liquid nitrogen for 20 minutes, diluting reacted mixture with the solvent, and resuspending three times in acetone, n-hexane, and recovering crude product by centrifugation, placing crude product under vacuum at 40 degrees C for 8 hours to obtain copolymerization product first; and (B) dissolving copolymerization product first, ethylenediaminetetraacetic acid disodium salt, and sodium tungstate dihydrate in methanol, and then ultrasonically dispersing for 30 minutes, adding 25 mL water dropwise every hour, and stirring suspension at room temperature for 48 hours, dialyzing the mixture against deionized water for 2 days to remove residual salts, and filtering recovered product and drying under vacuum at 40 degrees C overnight.
