NOVELTY - The method involves adding graphite substance into water or organic solvent. Ultrasonic working process is performed according to graphene smashing operation. Diluted solution of the graphite substance is determined by using a graphite layer, where concentration of graphite ranges from 0. 3-0. 6 mg/ml. The diluted graphite substance is mixed with a single graphite layer. Base material pre-heating process is performed according to graphene solution electric spraying function. A nozzle is coated with a substrate material to perform electric spraying process. USE - Graphene coating material preparation method. ADVANTAGE - The method enables increasing heat radiating effect and reducing production cost.
