NOVELTY - Preparing graphene involves mixing high-purity expanded graphite, anionic surfactant, dispersant, antifoaming agent, and tsolvent into the reaction vessel and mechanically stirring for 30-120 minutes to form a mixed slurry, crushingPreparing graphene involves mixing high-purity expanded graphite, anionic surfactant, dispersant, antifoaming agent, and tsolvent into the reaction vessel and mechanically stirring for 30-120 minutes to form a mixed slurry, crushing. USE - Method for preparing graphene. ADVANTAGE - The method enables to prepare graphene in cost-effective manner, and which has high manufacture efficiency. DETAILED DESCRIPTION - Preparing graphene involves mixing high-purity expanded graphite, anionic surfactant, dispersant, antifoaming agent, and tsolvent into the reaction vessel and mechanically stirring for 30-120 minutes to form a mixed slurry, crushingPreparing graphene involves mixing high-purity expanded graphite, anionic surfactant, dispersant, antifoaming agent, and tsolvent into the reaction vessel and mechanically stirring for 30-120 minutes to form a mixed slurry, crushing, placing the above mixed slurry in an oven for drying at a drying temperature of 100-150 degrees C, forming a solid after drying, and pulverizing the solid to form crushed particles having a particle size of 100 micrometer, mixing again, selecting cetyl alcohol, heating at 50-70 degrees C to melt, adding the crushing particles to the melted cetyl alcohol, and stirring for 60-120 minutes, mixing, reducing whales, where wax alcohol temperature is 3-15 degrees C so that crushing particles mixing with cetyl alcohol solidification, selecting the glass with high roughness placed in the bottom of the container, introducing small amount of deionized water into the container, cooling at -10-15 degrees C, adding deionizeddeionized water to form a thin ice plate, heating at 0 degrees C. The thin ice plate is taken out, and the surface of the thin ice plate that contacts the bottom of the container is a surface with high roughness, and placed in an environment with a temperature of -20-30 degrees C to the high roughness of the thin ice plate. The cyanol particles of the oil-comminuted particles is coated on the surface of the degree, formed, placed cetyl alcohol-coated thin ice plate in a mixture of deionized water and ethanol, and gradually heated solution formed by mixing deionized water and ethanol to gradually melt the thin ice plate and cetyl alcohos, crushed particles in cetyl alcohol are suspended on the surface of a mixture of deionized water and ethanol, filtered, and rapidly dried to obtain final product.
