摘要：

In this work, TiO2 nanoparticles modified with octadecylamine and dodecyl mercaptan (DDM/ODA@PDA@TiO2 NPs) are uesd to improve the tribological properties of the white oil. The DDM/ODA@PDA@TiO2 NPs which are simply prepared by mussel inspired chemistry and the Michael addition reaction can be facilely dispersed in the white base oil. Tribological measurements showed that the dispersion of the white oil containing 3 wt% DDM/ODA@PDA@TiO2 NPs displays significant reductions in the friction coefficient and wear scar diameter at room temperature and 75 degrees C. Further XPS investigation shows that the favourable tribological properties of DDM/ODA@PDA@TiO2 NPs are ascribed to the synergistic effect of tribofilm (Fe2O3, Fe3O4, FeS2, FeS and FeSO4) and TiO2 nanofluids.
