AbstractA novel nanocomposite, CDs-La-EDTA, was synthesized by bonding carbon dots to the functional sites of rare earth complexes, and its tribological characteristics were evaluated as lubricant additives. The results showed that the mean friction coefficient and the wear scar diameter of lubricating oil containing 0.15 wt% CDs-La-EDTA were reduced by 14% and 22%, respectively, compared with those of the base oil. Furthermore, the dual lubrication mechanism of the nanocomposite was proposed. The rolling or sliding effect of rare earth nanofibrous rods and the mending effect of carbon dot particles contributed to excellent lubrication performance.
