▎ 摘　　要

NOVELTY - Solid lubricant comprises graphene quantum dots, fluorinated graphene quantum dots and nano molybdenum disulfide. USE - The solid lubricant is useful in electronic appliances operating under vacuum, radiation, strong magnetic fields, ultra high temperature, ultra low temperature, high rotational speed, high chemical corrosion and/or salt spray corrosion environments, lubricating oil and grease (all claimed). ADVANTAGE - The lubricant: has adjustable conductivity; and achieves a balance between electrical conductivity and insulation performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing solid lubricant comprising mixing graphene quantum dots, fluorinated graphene quantum dots and nano molybdenum disulfide to obtain the solid lubricant.
