▎ 摘  要

NOVELTY - Graphene conductive polymer composite material comprises 80-100 pts. wt. modified polystyrene and 3-5 pts. wt. modified graphene. The graphene conductive polymer composite material is prepared by dissolving modified polystyrene in N,N-dimethylformamide, adjusting the pH value to be alkaline, adding modified graphene under stirring, removing the filtrate by filtration, and extruding the substrate to obtain granules graphene conductive polymer composite materials. p-Hydroxystyrene is dissolved in dimethyl sulfoxide with potassium hydroxide solution under stirring, and then added epichlorohydrin to obtain intermediate 1. The gum arabic powder and sodium chloride aqueous solution are mixed under stirring, and added intermediate 1, styrene, anti-oxidation synergist, and benzoyl peroxide at elevated temperature to prepare pretreated polystyrene. USE - Graphene conductive polymer composite material. ADVANTAGE - The hindered phenol in the antioxidant synergist can terminate the oxidation reaction of the polymer material, and at the same time absorb ultraviolet light, convert light energy into heat energy and release it, thus preventing the aging of the polymer material, and ensuring the material able to conduct electricity normally. DETAILED DESCRIPTION - Graphene conductive polymer composite material comprises 80-100 pts. wt. modified polystyrene and 3-5 pts. wt. modified graphene. The graphene conductive polymer composite material is prepared by dissolving modified polystyrene in N,N-dimethylformamide, adjusting the pH value to be alkaline, adding modified graphene under stirring, removing the filtrate by filtration, and extruding the substrate to obtain granules graphene conductive polymer composite materials. p-Hydroxystyrene is dissolved in dimethyl sulfoxide with potassium hydroxide solution under stirring, and then added epichlorohydrin to obtain intermediate 1. The gum arabic powder and sodium chloride aqueous solution are mixed under stirring, and added intermediate 1, styrene, anti-oxidation synergist, and benzoyl peroxide at elevated temperature to prepare pretreated polystyrene. The obtained reaction mixture is added to ammonium persulfate to carry out the reaction, and dialyzed with distilled water to obtain the modified polystyrene styrene. An INDEPENDENT CLAIM is included for a method for preparing graphene conductive polymer composite material, which involves mixing and stirring isophorone diisocyanate and hydroxyethyl acrylate, adding dibutyltin dilaurate dropwise and citric acid to obtain intermediate 2, mixing and stirring resorcinol, aluminum chloride, and dichloromethane, add cyanuric chloride, adding substrate to deionized water, filtering the filtrate, and removing the bottom product, and then recrystallizing with tetrahydrofuran to obtain intermediate 3, mixing intermediate 3, 2,6-di-tert.-butyl-4-bromomethylphenol, potassium carbonate, and N,N-dimethylformamide to prepare intermediate 4, and mixing the intermediate 4, benzyl alcohol, dichloromethane, and aluminum chloride to obtain an antioxidant synergist.
