Macroscale Superlubricity of Hydrated Anions in the Boundary Lubrication Regime
ACS Applied Materials & Interfaces, 2023Cations can achieve excellent hydration lubrication at smooth interfaces under both microscale and macroscale conditions due to the boundary layer composed of hydration shells surrounding charges, but what about anions? Commonly used friction pairs are negatively charged at the solid/solution interface. Achieving anionic adsorption through constructing

Macroscale Liquid Superlubricity Achieved With Mixtures of Fructose and Diols
Wear, 2021Abstract Superlubricity has numerous benefits in industrial applications, but its practical applications are restrained from its heavy dependence on special atmosphere environment and the use of low-dimensional materials. This paper reports a novel and facile method to macroscale liquid superlubricity for steel tribopairs, which realizes superlow ...

In-Situ Formation of Tribofilm With Ti3C2Tx MXene Nanoflakes Triggers Macroscale Superlubricity
Tribology International, 2021Abstract In the present work, a robust macroscale superlubricity state was achieved with a coefficient of friction (COF) of 0.002 by introducing Ti3C2Tx MXene nanoflakes in glycerol at Si3N4/sapphire interfaces. The MXene-glycerol solution results in the reduction of COF by 96.90% and 97.87% compared to those of pristine glycerol and Ti3C2Tx MXene ...

Achieving macroscale liquid superlubricity using glycerol aqueous solutions
Tribology International, 2021Abstract In this work, we explored macroscale liquid superlubricity using glycerol as the base lubricant to form aqueous solutions with different water/glycerol weight ratios. We find that glycerol aqueous solutions with water/glycerol weight ratio of 0.2 achieves superlubricity (coefficient of ...

Macroscale superlubricity induced by film-forming polymer brush-grafted colloidal additives
Journal of Colloid and Interface Science, 2023Modifying surfaces with concentrated polymer brushes (CPBs) is an effective way to reduce friction of tribo-pairs lubricated with liquids. We investigate the hypothesis that colloids grafted with CPBs (hybrid colloids) can deposit onto tribo-substrates by varying the solvent quality with respect to the polymer, in order to obtain ultra-low coefficients

Macroscale Superlubrication Achieved with Shear‐Thinning Semisolid Lubricants
Advanced MaterialsAbstract Macrosuperlubric materials are pivotal for reducing friction and wear in engineering applications. However, current solid superlubricants require intricate fabrication and specific conditions (e.g., vacuum or inert atmospheres), while liquid superlubricants are prone to creep, leakage, and corrosion. Here,

Macroscale solid superlubricity from the perspective of tribochemistry
Advances in Colloid and Interface ScienceSuperlubricity, featuring near-zero friction, has attracted much attention due to its effectiveness in addressing energy crises. The underlying mechanism of solid superlubricity is incommensurate contact. Nowadays, relying on incommensurability and weaken size effect by reducing the contact area is an effective strategy for constructing macroscale ...
