▎ 摘　　要

NOVELTY - Manufacturing process of graphene raw material comprises (i) selecting the soft texture, where the surface color is dark gray, greasy, can pollute the paper, and the hardness is 1-2, the hardness can increase to 3 to 5, and the specific gravity is 1.9-2.3 along the vertical direction with the increase of impurities and the specific surface area is concentrated in the graphite block of 1-20 m2/g; (ii) subjecting the graphite block selected in the step (i) to precision cutting processing, and precisely cutting the graphite block into graphite flakes; (iii) applying pyrolytic graphite to the surface of the graphite flakes prepared in the step (ii) to make the graphite flakes rub against the pyrolytic graphite; and (iv) rubbing the graphite flakes with pyrolytic graphite in the step (iii) placed in a static state for a period of time, where the crystals are formed on the surface of the graphite flakes, and the crystals are the graphene raw materials. USE - The method is useful for manufacturing process of graphene raw material.
