Tuning the nanostructure and tribological properties of a non-ionic deep eutectic solvent with water addition

The addition of water to a non-ionic N-oxide deep eutectic solvent(DES) composed of phenylacetic acid (PhAA) and N-dodecylmorpholine-N-oxide(MO-12) in a 1:1 M ratio(PhAA/MO-12) will promote interfacial nanostructure formation due to increased proton transfer and solvophobic interactions, leading to reduced friction.
