Summary: Black phosphorus (BP) with a layered structure has been used as a lubrication additive, with BP nanosheets showing excellent lubrication performance in water-based lubrication additives. However, the tribological properties of BP-WL reduce gradually with increasing load due to nanosheet agglomeration. The friction reduction is primarily attributed to low interlaminar shear and adsorption of BP nanosheets, with a tribochemical reaction film effectively protecting the surface of titanium alloy/steel from wear.

Summary: As an emerging class of two-dimensional materials, MXenes show great potential in lubrication systems for their excellent antifriction and wear resistance. However, achieving stable dispersion of MXenes in base oils remains a challenge. In this study, the microstructure of MXene was modulated through in-situ growth of hydroxysalts, forming a heterostructure that significantly improved dispersion stability in poly-alpha-olefin-10 base oil. The obtained MXene/hydroxysalts composite exhibited steady and reduced friction coefficient as well as decreased wear track dimensions, showing promise as a lubricant additive.

Summary: In this study, MXene@Cu nanocomposites were prepared by electrostatic adsorption and in-situ reduction. The MXene nanosheets successfully adsorbed Cu2+ and then underwent in-situ reduction to form Cu nanoparticle attached MXene hybrids. The MXene@Cu exhibited excellent tribological performance, reducing friction coefficient and wear volume loss. This can be attributed to the synergistic effect of MXene nanosheets and Cu nanoparticles, which form a stable protective film on the worn surface.

Summary: Transition metal carbides, nitrides and carbonitrides (MXenes) have attracted significant attention in tribology and solid lubrication due to their low shear strength and ability to form wear-resistant tribo-layers. However, their use as lubricant additives is limited by their hydrophilic nature. To overcome this limitation, researchers have focused on the tuneable surface chemistry of MXenes to improve their dispersion stability and phase compatibility, resulting in enhanced tribological performance.

Summary: Four types of carbonized polymer dots (CPDs) with good dispersibility and long-term stability were successfully synthesized using saccharides as precursors, showing enhanced anti-wear and friction-reducing performances when added to polyethylene glycol. The synergy between the interfacial adsorption of polymeric shells, nano-lubrication effects of carbon cores, and establishment of CPDs-inserted tribofilm contribute to their superior lubricity and durability. This study provides insight into the lubrication mechanism of CPDs and offers a green strategy for their practical application in tribology.
