Why is Superlubricity of Diamond‐Like Carbon Rare at Nanoscale?

Small, Volume 20, Issue 33, August 15, 2024.
Diamond‐like carbon coating (DLC) exhibits notably distinct frictional behavior across macro‐, micro‐, and nanoscale friction tests conducted in inert gas environments. This peculiar dependence of DLC friction on the sliding contact scale is attributed to the instability of transfer films within the small contact area at the nanoscale, which hinders ...

Unravelling High-Load Superlubricity of Ionic Liquid Analogues by In Situ Raman: Incomplete Hydration Induced by Competitive Exchange of External Water with Crystalline Water

, 2023
A high load-carrying capacity is the key to the practicality of liquid superlubricity, but it is difficult to achieve high load and low friction simultaneously by relying solely on a liquid film.

Graphene-Graphene Interactions: Friction, Superlubricity and Exfoliation [PDF]

, 2018
Graphite's lubricating properties due to the "weak" interactions between individual layers have long been known. However, these interactions are not weak enough to allow graphite to readily exfoliate into graphene on a large scale.
