NOVELTY - The preparation of poly (p-phenylene terephthalamide) modified graphene involves dissolving p-phenylene diamine and terephthalolyl chloride in N-methyl-2-pyrrolidone, cooling, dripping golden 2,4,6-trichlorophenol solution, reacting, stirring, adding graphene oxide in water to obtain dark brown graphene oxide aqueous solution, adding to pyridinium p-toluenesulfonate solution, adding N,N'-dicyclohexylcarbodiimide as catalyst, reacting, adding hydrazine hydrate, re-reacting, N-methyl-2-pyrrolidone multiple washing, pumping, and vacuum drying at 80 degrees C. USE - Preparation of poly (p-phenylene terephthalamide) modified graphene (claimed). ADVANTAGE - The method enables preparation of poly (p-phenylene terephthalamide) modified graphene with high dispersibility in organic solvent. DETAILED DESCRIPTION - The preparation of poly (p-phenylene terephthalamide) modified graphene involves dissolving 1.5 mmol p-phenylene diamine and 1 mmol terephthalolyl chloride in 50 ml of N-methyl-2-pyrrolidone, cooling at 0 degrees C in ice bath, dripping golden 2,4,6-trichlorophenol solution to pyridine dithioethylamine solution, stirring, adding 2,4,6-trichlorophenol so that pink pyridine dithioethylamine solution is gradually turned to dark green,, reacting, stirring at room temperature for 30 minutes to complete the reaction, adding 0.05 graphene oxide in 10 ml water for half an hour to obtain dark brown graphene oxide aqueous solution, adding graphene oxide aqueous solution into pyridinium p-toluenesulfonate solution, adding 5 mg N,N'-dicyclohexylcarbodiimide as catalyst, reacting at 80 degrees C for 24 hours under nitrogen atmosphere, adding 0.1 ml hydrazine hydrate, re-reacting for 3 hours, N-methyl-2-pyrrolidone multiple washing and pumping, and vacuum drying at 80 degrees C.
