Superlubricity in Gemini Hydrogels

Journal of Tribology, 2016
Gemini 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 ...

Superlubricity: a state of vanishing friction

Wear, 2000
Abstract The state of vanishing friction called “superlubricity” is discussed from theoretical and experimental viewpoints. We study the friction system consisting of two contacting surfaces, and derive the condition for the non-adiabatic motion of atoms to occur.

Superlubrication by phonon confinement

Physical Review B, 2018
The superlubrication described here, involving confined phonons, is easily achievable and very simple because it uses only submicron islands, smaller than the mean free path of the phonons, to confine phonons. We can achieve superlubrication with a friction force of piconewton order at the submicron island. We can call this phononic lubrication or self-

High‐Temperature Superlubricity Microcapsules

Small
Abstract Superlubricity, 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

Friction Process of Superlubricity

ASME/STLE 2012 International Joint Tribology Conference, 2012
The 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.
