TLDR
In this article, the impact of a liquid drop of low viscosity on a super-hydrophobic surface was studied. But the authors focused on the effect of the drop on the spread of the liquid on the surface.Abstract:
We first study the impact of a liquid drop of low viscosity on a super-hydrophobic surface. Denoting the drop size and speed as are the liquid density and surface tension). This law is also observed to hold on partially wettable surfaces, provided that liquids of low viscosity (such as water) are used. The law is interpreted as resulting from the effective acceleration experienced by the drop during its impact. Viscous drops are also analysed, allowing us to propose a criterion for predicting if the spreading is limited by capillarity, or by viscosity.read more

Spreading Time of Liquid Droplets Impacting on Non-wetting Solid Surfaces
TL;DR: In this paper, the authors study the impact of a liquid droplet on a super-hydrophobic surface and demonstrate that the spreading time is jointly determined by the inertial, capillary and viscous forces.

One-Step Fabrication of Hot-Water-Repellent Surfaces
TL;DR: In this paper , a facile and fluorine-free one-step vapor-deposition method was proposed for fabricating excellent hot-water-repellent surfaces, which at room temperature even repel water droplets of temperature up to 90 °C as well as other normal-temperature droplets with surface tension higher than 48.4 mN/m.
