▎ 摘　　要

NOVELTY - Screening of oil-soluble graphene, involves mixing graphene, a base oil, and a dispersant to obtain a uniform solution, adding the solution to a wall breaker or a ball mill, and centrifuging to remove precipitate and obtain suspension. USE - Screening of oil-soluble graphene for use in lubricating oil. ADVANTAGE - The method enables easier removal of surface valence electrons when compared with immersion method, to achieve better dispersion of oil solvent.
