▎ 摘　　要

NOVELTY - Preparing lubricating oil containing modified graphene comprises adding modified graphene into first part of 150 N base oil and dispersing uniformly to obtain lubricant. The modified graphene is prepared by taking graphene oxide as raw material, doping and reducing by phosphorus and molybdenum selenide to obtain doped graphene, then modifying doped graphene and second part of 150 N base oil with polyaniline to obtain modified graphene. USE - The method is useful for preparing lubricating oil containing modified graphene. ADVANTAGE - The lubricating oil containing modified graphene: has excellent lubrication and anti-wear effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for lubricating oil containing modified graphene obtained by above method.
