NOVELTY - High speed stripping of graphene comprises mixing white graphene (hexagonal boron nitride) powder, surfactant and dispersion medium, then stirring and peeling under high speed conditions, the stirring process uses ice water to reduce the temperature of the system, and the total stirring time is 10-240 hours; or spraying and peeling under a pressure of more than 50 MPa high pressure homogenizer, after the completion of the peeling, washing the resulting slurry with alcohol and then drying to obtain white graphene powder, where the high-speed stripping is agitation stripping under high-speed conditions, the stirring and stripping under a stirring speed of 5000-18000 revolutions/minute, and the mass ratio between white graphene (hexagonal boron nitride) powder and surfactant is 1:50-10:1 (preferably 1:1-500:1); and the mass ratio between white graphene (hexagonal boron nitride) powder and dispersion medium is 1:100-1:2000 (preferably 1:3-1:500). USE - The method is useful for high speed stripping of graphene. ADVANTAGE - The graphene: has small number of layers, large specific surface area, large particle size and complete crystal structure; and the stripping method is simple and rapid.
