Structural Superlubricity Based on Crystalline Materials
Small, 2019AbstractHerein, structural superlubricity, a fascinating phenomenon where the friction is ultralow due to the lateral interaction cancellation resulted from incommensurate contact crystalline surfaces, is reviewed. Various kinds of nano‐ and microscale materials such as 2D materials, metals, and compounds are used for the fabrication.

Superlubricity: when friction stops
Physics World, 1997The frictional properties of materials were first scientifically described by Leonardo da Vinci over 400 years ago. Since then, a wealth of experimental data have shown that a force must be applied for two bodies in contact to slide past each other with constant velocity: in other words, energy is dissipated during friction. Although the role of atomic

Superlubricity in Gemini Hydrogels
Journal of Tribology, 2016Gemini hydrogels have repeatedly produced low friction under conditions generally not thought to be favorable to superlubricity: low sliding speeds, low contact pressures, macroscopic contact areas, and room temperature aqueous environments. A proposed explanation for this unique behavior is that thermal fluctuations at the interface are sufficient to ...

Friction Process of Superlubricity
ASME/STLE 2012 International Joint Tribology Conference, 2012The friction process of superlubricity (μ = 0.004) obtained by phosphoric acid solution has been investigated by a traditional tribometer. The evolution of friction coefficient with time indicates that the friction process of superlubricity is divided into three stages, i.e.

High‐Temperature Superlubricity Microcapsules
SmallAbstractSuperlubricity, characterized by an ultra‐low coefficient of friction (COF) below 0.01, is crucial for reducing energy losses in mechanical systems but remains challenging at high temperatures. This study designed a high‐temperature‐resistant solid–liquid coupled microcapsule containing perfluoropolyether (PFPE) and molybdenum disulfide (MoS2 ...
