A Systematic Review of the Recent Advances in Superlubricity Research

Coatings, 2023
Friction and the wear caused by friction will not only lead to energy dissipation, but will also cause damage to the function of mechanical parts, affecting the precision and lifespan of mechanical devices.

Nanomaterials in Superlubricity

Advanced Functional Materials, 2019
AbstractThe vanishing friction, known as superlubricity, is potentially a significant performance indicator in the development of nanostructured materials and has become increasingly important for realizing energy saving and extending the life of mechanical components.

Advancements in superlubricity

Science China Technological Sciences, 2013
Superlubricity is a new area in tribology, in which the slide friction coefficient is about 1/1000 to 1/100 of the general ones. Since the concept of superlubricity was proposed, it has attracted more and more attentions from researchers in fields of tribology, physics, chemistry, materials, etc.

Superlubricity of molybdenum disulphide

Physical Review B, 1993
We have studied the atomistic origins of the ultralow friction coefficient of a molybdenum disulphide (${\mathrm{MoS}}_{2}$) coating in ultrahigh vacuum conditions. A friction coefficient in the ${10}^{\mathrm{\ensuremath{-}}3}$ range is associated with friction-induced orientation of ``easy shear'' basal planes of the ${\mathrm{MoS}}_{2}$ crystal ...

Superlubricity Microcapsules

ACS Applied Materials & Interfaces
Superlubricity, a lubricating state in which the coefficient of friction (COF) is smaller than 0.01, has been achieved at the macroscale in a variety of aqueous solutions and oils, as well as two-dimensional (2D) and carbon materials; nevertheless, it has been rarely realized with polymer composites.

Superlubricity of Ice

2016
Superlubricity means non-sticky and frictionless when two bodies are set contacting motion. Although this occurrence has been extensively investigated since 1859 when Faraday firstly proposed a quasiliquid skin on ice, the mechanism behind the superlubricity remains debating.

Collective superlubricity of graphene flakes

Journal of Physics: Condensed Matter, 2016
We investigate solid lubrication of graphene and graphene flakes using atomistic molecular-dynamics simulations. We find that graphene flakes yield lower friction than graphene as a result of a collective mechanism that emerges from the independent behaviour of the flakes.

Robust superlubricity by strain engineering

Nanoscale, 2019
We demonstrate that robust superlubricity can be achieved via both biaxial and uniaxial tensile strains in a substrate using molecular dynamics simulation. Above a critical strain, the friction is no longer dependent on the relative orientation between the surfaces mainly due to the complete lattice mismatch.
