Water skin anomalies: density, elasticity, hydrophobicity, thermal stability, interface repulsivity, etc

TL;DR

This paper explores the unique properties of water skins, such as density, elasticity, and hydrophobicity, using a unified theoretical framework to explain their behavior and interactions at interfaces.

Contribution

It introduces the BOLS-NEP model that unifies existing theories and explains controllable transitions between hydrophobic and hydrophilic states of water skins.

Findings

Water skins exhibit supersolid behavior influenced by bond relaxation and polarization.

The BOLS-NEP model unifies classical wetting theories.

Controllable transition between hydrophobicity and hydrophilicity is explained.

Abstract

Molecular undercoordination induced O:H-O bond relaxation and dual polarization dictates the supersolid behavior of water skins interacting with other substances such as flowing in nanochannels, dancing of water droplets, floating of insects. The BOLS-NEP notion unifies the Wenzel-Cassie-Baxter models and explains controllable transition between hydrophobicity and hydrophilicity.
