Exploring Nanoscale Lubrication Mechanisms of Multilayer MoS₂ During Sliding: The Effect of Humidity.

ABSTRACT: Solid lubricants have received substantial attention due to their excellent frictional properties. Among others, molybdenum disulfide (MoS₂) is one of the most studied lubricants. Humidity results in a deterioration of the frictional properties of MoS₂. The actual mechanism at the nanoscale is still under debate, although there are indications that chemical reactions are not likely to occur in defect-free structures. In this study, we performed nonequilibrium molecular dynamics simulations to study the frictional properties of multilayer MoS₂ during sliding in the presence of water. Moreover, we also investigated the effect of sliding speed and normal load. We confirmed earlier results that a thin layer of water organizes as a solidified, ice-like network o
