▎ 摘　　要

NOVELTY - A high dispersion modified graphene lubricating oil comprises modified graphene, base oil and dispersant. The addition amount of modified graphene is 3-15 wt.% of base oil. The addition amount of dispersant is 0.5-1.0 wt.% of base oil. USE - High dispersion modified graphene lubricating oil (claimed). ADVANTAGE - The high dispersion modified graphene lubricating oil has excellent dispersibility and high stability and solves the long-term stability problem of graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of high dispersion modified graphene lubricating oil, which involves dispersing modified graphene into base oil, stirring uniformly to obtain mixed solution, carrying out microwave irradiation of mixed solution, stirring for 20-30 minutes and adding stearic acid-modified titanium dioxide nanoparticles.
