Abstract
In order to promote the formation of high-quality graphene-based self-lubricating transfer film. The reduced graphene oxide (RGO) deposited with molybdenum disulfide quantum dots (MoS2QDs) were successfully prepared. The as-prepared MoS2QDs/RGO hybrid was used for the first time to improve the tribological properties of polymer composites. Compared with the neat bismaleimide (BMI) and RGO filled composites, the MoS2QDs/RGO/BMI showed the best tribological properties, and the frictional coefficient and volume wear rate could be decreased to 0.15 and 8.9 × 10−6 mm3/(N·m), respectively. This is mainly due to the MoS2QDs loaded on the graphene surface are beneficial to prevent the graphene nanosheet stacking, and the introduction of MoS2QDs can make the self-lubricating transfer film formed more uniform, smooth and robust during the friction process.
