NOVELTY - The preparation method of resin graphene-metal composite material involves adding concentrated sulfuric acid, graphite and sodium nitrate to a beaker and then stirring, adding potassium permanganate to the mixture and then stirring, adding distilled water to the mixture and then diluting, adding hydrogen peroxide to the mixture and then washing using hydrochloric acid and deionized water, adding dehydrated N,N-dimethylformamide, PTFE, polyetheretherketone, polystyrene, hydrogen peroxide, dispersant and deionized water to the mixture and then heating, and drying. USE - The method is useful for preparation of resin graphene-metal composite material. ADVANTAGE - The method enables preparation of resin graphene-metal composite material with excellent electrical properties and conductivity. DETAILED DESCRIPTION - The preparation method of resin graphene-metal composite material involves adding 200 ml concentrated sulfuric acid, 10 g graphite and 7 g sodium nitrate to a beaker and then stirring, adding 20 g potassium permanganate to the mixture and then stirring for 2 hours, adding 200 ml distilled water to the mixture and then diluting using 1000 ml distilled water, adding 30 g hydrogen peroxide to the mixture and then washing using 5% hydrochloric acid and deionized water, adding 100 ml dehydrated N,N-dimethylformamide, 3-6 pts. wt. PTFE, 2-5 pts. wt. polyetheretherketone, 1-3 pts. wt. polystyrene, 1-2 pts. wt. hydrogen peroxide, 1-2 pts. wt. dispersant and 7-10 pts. wt. deionized water to the mixture and then heating, washing using 0.3% hydrochloric acid solution and deionized water, and drying at 65 degrees C.
