NOVELTY - Preparing super wear-resistant self-lubricating material comprises (a) dispersing molybdenum disulfide powder in an organic solvent, cooling the product system, centrifuging, taking the supernatant to obtain a solution containing molybdenum disulfide quantum dots, adding the solution containing molybdenum disulfide quantum dots and graphene oxide into a good solvent, adding a reducing agent to reduce graphene oxide to obtain particles containing molybdenum disulfide quantum dots/graphene oxide product system, filtering to save the filter residue, washing the filter residue, freeze-drying and (b) uniformly mixing molybdenum disulfide quantum dots/graphene particles and polymer matrix material, molding the disulfide and processing to obtain molybdenum quantum dot/graphene/polymer-based super wear-resistant self-lubricating material. USE - The material is useful as a super wear-resistant mechanical part (claimed). ADVANTAGE - The method: is simple and convenient for large-scale production and has universal applicability. The material has a reduced friction coefficient of 51-63%; reduces the volume wear rate by 70-95% and broadens the application of polymer material. DETAILED DESCRIPTION - Preparing super wear-resistant self-lubricating material comprises (a) dispersing molybdenum disulfide powder in an organic solvent, using the ultrasonic-solvothermal method to obtain a product system containing molybdenum disulfide quantum dots, cooling the product system, centrifuging, taking the supernatant to obtain a solution containing molybdenum disulfide quantum dots, adding the solution containing molybdenum disulfide quantum dots and graphene oxide into a good solvent for uniform dispersion to obtain a mixed system, adding a reducing agent to the mixed system to reduce graphene oxide to obtain particles containing molybdenum disulfide quantum dots/graphene oxide product system, filtering the product system to save the filter residue, washing the filter residue, freeze-drying to obtain molybdenum disulfide quantum dots/graphene particles and (b) uniformly mixing molybdenum disulfide quantum dots/graphene particles and polymer matrix material, molding the disulfide and processing to obtain molybdenum quantum dot/graphene/polymer-based super wear-resistant self-lubricating material. An INDEPENDENT CLAIM is also included for a super wear-resistant and self-lubricating material prepared by the above method.
