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

Dynamic behavior of the water droplet impact on a textured hydrophobic/superhydrophobic surface: the effect of the remaining liquid film arising on the pillars' tops on the contact time.

TL;DR: Experimental results validated that the remaining liquid film on the pillars' tops gave rise to a wet surface instead of a dry surface as the water droplet began to recede away from the textured surfaces.

Drop Impact and Rebound Dynamics on an Inclined Superhydrophobic Surface
TL;DR: Investigating the impact and rebound dynamics of a drop at various liquid viscosities, in an isothermal environment, and on a nanocomposite superhydrophobic surface at normal and oblique impact conditions revealed that oblique and normal drop impact behaved similarly (in terms of maximum drop spread as well as rebound dynamics) at low normal Weber numbers.

Microscopic structure influencing macroscopic splash at high Weber number
TL;DR: In this article, the dynamics of water drop impact at high impinging velocity onto superhydrophobic substrates is experimentally investigated, and quantitative results of the entrapped air bubble, the central wetted area, and the maximal spreading lamella as the impact velocity is increased.

TL;DR: In this paper, the authors present an experimental study of drop impact on a solid surface in the spreading regime with no splashing, using the space-time-resolved Fourier transform profilometry technique.
