Summary
Based on the redox capability of dopamine in a weak alkaline atmosphere, silver nanoparticles have been uniformly loaded on the floor of polydopamine-modified graphene oxide (Ag/PGO). The outcomes present that the bottom oil containing Ag/PGO nanoparticles displays a greater tribological property than base oil. The utmost lower in put on charge and friction coefficient at totally different temperatures amounted to 68% and 53.6%, respectively. The tribofilm containing C, O, N, and Ag exists and performs an essential function in lowering friction and growing put on resistance. Molecular dynamics simulations present that the microscopic oil movie composed of Ag/PGO and n-hexadecane has low shear deformation throughout the shearing course of, and the oil movie has low interplay power with the higher and decrease shear partitions.
