Nanolubrication in deep eutectic solvents

Abstract

We report surface force balance measurements of the normal surface force and friction between two mica surfaces separated by a nanofilm of the deep eutectic solvent ethaline.

Ionic liquids and deep eutectics as a transformative platform for the synthesis of nanomaterials

“…225 Further structural insights will soon be attainable via computational methodologies such as AIMD (ab-initio molecular dynamics) 210 and MD (molecular dynamics) with polarisable force fields, 226,227 in combination with experimental scattering data, 207 with synergy between these bulk studies and those of the interface. 221,228,229…”

“…16) while improving transport properties and is thus potentially appealing in materials synthesis, where the precipitation of nanoparticles in an already highly viscous medium can cause handling difficulties. However, the addition of water can affect the interfacial structure significantly, [218][219][220] and thus play a role in nanomaterial synthesis (notwithstanding effects such as the increased surface tension reducing nucleation rates). That is not to say that DES cannot be nanostructured nor that ILs must be.…”

Green and Economical Bet-Based Natural Deep Eutectic Solvents: A Novel High-Performance Lubricant

“…Indepth research on the tribological mechanism of DESs was always missing. Hallett et al 13 explored the friction behavior between two mica surfaces separated by a nanofilm of ChCl-Ethylene glycol DES. DES with 50% water exhibited superlubricity because the excess water disrupted the DES structure, resulting in the separation of water layers and favoring in-plane flow.…”

Solvation Structure, Dynamics, and Charge Transfer Kinetics of Cu2+ and Cu+ in Choline Chloride Ethylene Glycol Electrolytes

“…Type III deep eutectic solvents (DESs), mixtures of hydrogen bond acceptors such as choline chloride (ChCl) and hydrogen bond donors, have drawn extensive attention over the past two decades due to their potential for applications in a wide variety of fields. − In particular, their favorable properties such as low volatility, low flammability, and electrochemical and thermal stability under common working conditions make them ideal options as battery electrolytes. − …”
