The graphene lubricant currently exists on the market mainly through the flake/globular material mixed addition (such as graphene/barium sulfate), surface grafting treatment (isocyanate, diazonium salt and other surface modification) and other methods to improve the dispersion of graphene, but due to the difficulty of preparation of high purity graphene, dispersant additive is easy to affect the stability of the system and other factors affect the performance of the product is not as satisfactory as the actual obtainment of product performance. Most of the graphene lubricants have empty names but no practical application value, improper use will cause damage to the car engine.
