“…1,2 For the past decades, nanoparticles have attracted considerable attention as potential oil additives due to their excellent physical and chemical properties. 3 In respect of this, the layered nanoparticles based on strong intraplanar and weak interplanar bonds, such as graphite and its derivatives, 4 hexagonal boron nitride, 5 zirconium phosphates, 6 layered double hydroxides, 7 and transition metal dichalcogenides 8,9 have been recognised as promising alternatives for traditional oil additives. Molybdenum disulfide (MoS 2 ) nanoparticles, as a typical member of transition metal dichalcogenides, are known to enhance the tribological properties of oils in virtue of their excellent frictionreducing and antiwear properties.…”

Molybdenum disulfide (MoS2) nanoparticles are widely used as oil additives for obtaining low friction and wear. In this article, MoS2 nanosheets with ultrathin shape and structure defects were prepared by a facile solvothermal method with the aid of polyethylene glycol (PEG 200). The products were analysed by X‐ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), X‐ray photoelectron spectroscopy (XPS), and Fourier transform infrared (FTIR). Results indicated that PEG 200 played a crucial role as the shape controller in the formation of different MoS2 structures. Interestingly, the prepared MoS2 perform excellent in improving the friction‐reducing and antiwear properties of oils. More importantly, the lubricating behaviour of the obtained MoS2 nanosheets as oil additives was still effective in the harsh condition of heavy load and high temperature. Further, the excellent lubrication performance of the prepared MoS2 was discussed based on the exfoliation into individually ultrathin nanosheets and nanosized debris, and the formation of MoS2‐based tribofilm inside the wear tracks.

“…In order, to improve the dispersibility and stability of MoS 2 , Wu et al [100] used oleic diethanolamide (OD) to modify MoS 2 nanosheets, thereafter study the tribological behavior in base-oil using a four-ball tester. The results showed that the average COF and average wear scar diameter of 0.08 wt.% OD-MoS 2 -based oil were reduced by ~36.8% and ~15.4% as compared with the base oil, respectively.…”

The exfoliation of graphene has opened a new frontier in material science with a focus on 2D materials. The unique thermal, physical and chemical properties of these materials have made them one of the choicest candidates in novel mechanical and nano-electronic devices. Notably, 2D materials such as graphene, MoS2, WS2, h-BN and black phosphorus have shown outstanding lowest frictional coefficients and wear rates, making them attractive materials for high-performance nano-lubricants and lubricating applications. The objective of this work is to provide a comprehensive overview of the most recent developments in the tribological potentials of 2D materials. At first, the essential physical, wear and frictional characteristics of the 2D materials including their production techniques are discussed. Subsequently, the experimental explorations and theoretical simulations of the most common 2D materials are reviewed in regards to their tribological applications such as their use as solid lubricants and surface lubricant nano-additives. The effects of micro/nano textures on friction behavior are also reviewed. Finally, the current challenges in tribological applications of 2D materials and their prospects are discussed.
