Quantifying Wetting Dynamics with Triboelectrification (Adv. Sci. 24/2022)

Quantifying Wetting Dynamics There exists an intrinsic link between wetting and charge generation due to fluid motion over surfaces made using triboelectric layers. In article number 2200822, Michele Scaraggi, Daoai Wang, Daniele Dini, Feng Zhou, and co-workers show that wetting dynamics can be accurately quantified and tracked using solid-liquid triboelectrification. Theoretical underpinning reveals how surface micro-/nano-geometries regulate stability/infiltration, also demonstrating the generality of the theoretical approach in understanding wetting transitions in real environments.
