▎ 摘　　要

NOVELTY - A high dispersibility and affinity modified graphene lubricating oil comprises modified graphene, base oil, affinity agent and dispersant. The amount of modified graphene is 3-15 wt.% of base oil. The amount of affinity agent is 0.1-2 wt.% of base oil. The amount of dispersant is 0.5-1.0 wt.% of base oil. USE - High dispersibility and affinity modified graphene lubricating oil (claimed). ADVANTAGE - The high dispersibility and affinity modified graphene lubricating oil has excellent dispersibility and high stability, and solves long-term stability problem of graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of high dispersibility and affinity modified graphene lubricating oil, which involves adding modified graphene, dispersant and affinity agent to base oil, stirring evenly to obtain mixed solution, stirring mixed solution under microwave irradiation for 20-30 minutes and adding stearic acid-modified titanium oxide nanoparticles.
