Graphene superlubricity: A review

Abstract

Superlubricity has drawn substantial attention worldwide while the energy crisis is challenging human beings. Hence, numerous endeavors are bestowed to design materials for superlubricity achievement at multiple scales. Developments in graphene-family materials, such as graphene, graphene oxide, and graphene quantum dots, initiated an epoch for atomically thin solid lubricants. Nevertheless, superlubricity achieved with graphene-family materials still needs fundamental understanding for being applied in engineering in the future. In this review, the fundamental mechanisms for superlubricity that are achieved with graphene-family materials are outlined in detail, and the problems concerning graphene superlubricity and future progress in superlubricity are proposed. This review concludes the fundamental mechanisms for graphene superlubricity and offers guidance for utilizing graphene-family materials in superlubricity systems.

Competition-Induced Macroscopic Superlubricity of Ionic Liquid Analogues by Hydroxyl Ligands Revealed by in Situ Raman

“…Superlubricants can be broadly classified into two categories: solid and liquid . For the former, typical ones include molybdenum disulfide, graphene, diamond-like carbon films, and multiwalled carbon nanotubes. − However, solid superlubricity materials usually require specific conditions (e.g., vacuum/inert gas atmosphere, incommensurate contact, micrometer size, and absolute surface rigidity) to achieve superlubricity, whereas the liquid ones easily achieve macroscopic superlubricity on routinely flat surfaces under atmospheric conditions such as aqueous phosphoric acid solutions . As a result, liquid superlubricants have a much greater potential than solid superlubricants to meet the real-world requirements of a wide range of applications and are compatible with most existing lubrication systems.…”

Atomistic simulations of the frictional properties of 2D materials: a review

“…To achieve the goal of reducing friction and mitigating wear, it calls for the finding of origin of friction from the atomic scale. Recently, superlubricity, a state of vanishing friction has drawn intensive attentions and been well investigated by experiments and atomistic simulations [2][3][4][5]. More specially, structural superlubricity * Authors to whom any correspondence should be addressed.…”

Antifoaming Agent for Lubricating Oil: Preparation, Mechanism and Application

“…Graphene-family additives can be dispersed well and stabilized in water-based lubricants due to hydrogen bond interactions [ 6 ]. However, for lubricating oils, graphene family additives are generally difficult to disperse and stabilize in oils [ 7 ]. Graphene oxide quantum dots (GOQDs) can be used as nano-additives to achieve macro super lubricity.…”
