Research on friction properties of silver/polydopamine modified graphene oxide nanocomposites as lubricant additive: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0




In response to the redox potential of dopamine in a weak alkaline surroundings, 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 price 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 position 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 through the shearing course of, and the oil movie has low interplay power with the higher and decrease shear partitions.
