NOVELTY - Milling white graphene comprises mixing the white graphene powder, surfactant and ball milling medium, dissolving, ball milling in a sealed ball mill, adding the ball milling media after each period of milling, where the addition of the ball mill medium is 5-40 wt.% of the white graphene and milling for 120-480 hours, washing the resulting powder with alcohol and drying. USE - The method is useful for milling white graphene (claimed). ADVANTAGE - The method: can effectively peel off white graphene particles; produces white graphene with uniform particles, few layers and large area and high purity; and can be dispersed in alcohol and other solvents to save dozens of days to not produce agglomeration settlement. DETAILED DESCRIPTION - Milling white graphene comprises (a) mixing the white graphene powder, surfactant and ball milling medium, dissolving, ball milling at a rate of 200-800 revolutions/minute in a sealed ball mill, where the mass ratio of the white graphene powder and the surfactant is 1:1-500:1 and the mass ratio of the white graphene and the ball milling medium is 2:1-1:10, (b) adding the ball milling media after each period of milling, where the addition of the ball mill medium is 5-40 wt.% of the white graphene and milling for 120-480 hours and (c) washing the resulting powder with alcohol and drying, to obtain white ball graphene dispersion.
