Abstract On hard solids, roughness increases wetting properties: hydrophilic substrates become more hydrophilic, hydrophobic become more hydrophobic. Above a critical roughness, poorly wetting substrates become almost non-wetting: deposited liquids remain at the top of the textures that cover the solid so that they are actually sitting on a cushion of air trapped inside the textures. The substrates are in this case called «superhydrophobic», they exhibit very interesting properties such as water-repellency, drag reduction, self-cleaning. In this presentation, we will discuss how the softness of a superhydrophobic substrate can modify its non (poor) wetting properties through three examples.
