▎ 摘 要
NOVELTY - Preparation of graphene/molybdenum disulfide composite material, comprising (i) dispersing graphene in water, adding molybdenum source and sulfur source and mixing evenly, then carrying out microwave reaction, naturally cooling to room temperature; (ii) washing and drying the product obtained in step (i). USE - The composite material is useful for lubricating oil additive (claimed). ADVANTAGE - The preparation and operation is simple and environmentally friendly, and the production efficiency is high. The obtained additive can be used in lubricating oil, and has the high dispersibility and stability, good friction reduction and anti-wear performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: preparing graphene/molybdenum disulfide/ionic liquid additive, comprising obtaining graphene/molybdenum disulfide composite material, mixing graphene/molybdenum disulfide composite material and ionic liquid and ball-milling; lubricating oil additive, comprising the graphene/molybdenum disulfide/ionic liquid additive; and lubricating oil, comprising base oil and the lubricating oil additive.
