▎ 摘　　要

NOVELTY - Preparation of lipophilic graphene nanosheet involves mixing flaky graphite powder and inorganic acid, reacting, adding persulfate, stirring, adding peroxide, leaving still, washing, drying to obtain pretreated graphite, adding intercalation removing agent, lipophilic improver and additive, mixing, washing mixture with water and drying. USE - Preparation of lipophilic graphene nanosheet used in lubricating grease, coatings and composite materials (claimed). ADVANTAGE - The method enables simple preparation of lipophilic graphene nanosheet with desired size of less than 500 nm and thickness of less than 10 nm, improved dispersibility and stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for lipophilic graphene nanosheet prepared by the method.
