▎ 摘  要

NOVELTY - Method for high-speed dispersion of white graphene, involves mixing white graphene powder, surfactant and dispersion medium, dissolving, stirring at 5000-18000 rpm for 10-240 hours, reducing temperature using ice water, grinding to obtain powder, washing powder with alcohol, performing centrifugal separation and drying. The mass ratio of white graphene powder and surfactant is 1:50-10:1. The mass ratio of white graphene and dispersion medium is 1:100-1:2000. USE - Method for high-speed dispersion of white graphene (claimed). ADVANTAGE - The method enables dispersing white graphene with high purity, and white graphene has large specific surface area. The graphene can be prepared with even granularity, and does not agglomerate even after 10 days.
