NOVELTY - Graphene/polymer composite material preparation involves taking 1-10g polymer added to 10-100ml organic solvent A. The obtained mixture stirred magnetically to dissolve. 1-500mg graphite oxide powder and 1-100ml organic solvent A are mixed. The obtained mixture is dispersed uniformly. The two solutions are mixed. The obtained mixture is stirred. The obtained anti-solvent precipitation composite material is filtered, washed, and then dried. 1-100mg composite material and 1-10ml reducing agent are added into the reaction kettle. USE - Method for preparing graphene/polymer composite material (claimed). DETAILED DESCRIPTION - Graphene/polymer composite material preparation involves taking 1-10g polymer added to 10-100ml organic solvent A. The obtained mixture stirred magnetically to dissolve. 1-500mg graphite oxide powder and 1-100ml organic solvent A are mixed. The obtained mixture is dispersed uniformly. The two solutions are mixed. The obtained mixture is stirred. The obtained anti-solvent precipitation composite material is filtered, washed, and then dried. 1-100mg composite material and 1-10ml reducing agent are added into the reaction kettle. The obtained mixture is introduced with inert gas at 150 degrees C for 2-50 minutes with 25 megapascal to 24 Harbor Freight. The reaction kettle is kept in ice-bath. The obtained mixture is filtered, washed, and then dried.
