NOVELTY - Preparing graphene model metal composite material involves adding graphene oxide into distilled water, ultrasonically dispersing uniformly to obtain dispersion liquid, where concentration of graphene oxide solution is 6-10mg/mL, dispersing into liquid nitrogen to freeze to solid, placing into freeze dryer at 1000-1200 kilowatts in vacuum for 8-12 hours for liquid to volatilized completely to obtai graphene oxide porous material. The 5-9 pts. wt. iron chloride, 8-12 pts. wt. manganese nitrate and 7-13 pts. wt. tungsten phosphate are added into 40-50 pts. wt. ethanol, stirring for 10-30 minutes. The 6-10 parts of ethylene-vinyl acetate copolymer is added, stirred continuously and reacted for 30-50 minutes at 80-100 degrees C to obtain mixed solution. The prepared graphene oxide porous material is added in mixed solution u8nder nitrogen atmosphere in tube furnace at 3-5 degrees C/minute. The temperature is reaised to 650-800 degrees C and calcined for 2-4 hours to obtain graphene-metal composite material. USE - Method for preparing graphene model metal composite material.
