Abstract
The objective of this study was to investigate a mechanism for enhancing the tribological properties of a green polymer material using MoS2, which is a common material with good tribological qualities. In this study, MoS2 nanoparticles were added to the biopolymer Hydroxypropyl Methylcellulose, obtaining an evident enhancement of the tribological behaviour. The suitable content of MoS2 can provide the best structure of the composite film and optimise the transfer layer, and further enhance the tribological properties. The addition of 5-10% MoS2 particles to the polymer can improve the surface roughness up to 60%, reduce the friction coefficient of the thin-film material by more than 40% and reduce the wear rate of the substrate by 65%. The mechanism by which MoS2 additives enhance the tribological properties of the biopolymer material lies in the reduction of the run-in time in the initial stage of wear by modifying the surface roughness. This effect accelerates the formation of a transfer layer of good quality and provides good tribological properties. 18 refs.
