Advances in the Study of Quantum Dots as Lubricant Additives: A Review

Abstract

The study of quantum dots as lubrication additives has gained much attention in recent years, and has shown potential advantages in the field of lubrication due to their excellent physical and chemical properties, especially at the nanoscale. Quantum dots are nanoscale semiconductor particles with quantum effects, which are usually between 2 and 10 nanometres in size, with a large specific surface area and a special electronic structure. As lubricant additives, quantum dots enhance lubrication performance by improving the viscosity of the lubricant, lowering the coefficient of friction, reducing wear, and improving corrosion and oxidation resistance. At present, the research of quantum dots as lubrication additives is still in the exploratory stage, but with the development of nanotechnology, the application of quantum dots in the field of lubrication is promising, especially in the field of aerospace, automotive, machinery and equipment and other high-performance requirements, which has an important potential for application. This paper reviews the research and development progress of quantum dots lubricant additives, as well as many successful applications of quantum dots lubricant additives at present, and focuses on the friction reduction and anti-wear performance, superiority and lubrication mechanism of quantum dots as lubricant additives.
