Droplets impacting on open-cell textured surfaces undergo a transition from the Cassie state to the Wenzel state whereby the surface gets impregnated by the liquid and temporarily loses its super-hydrophobicity. Cassie-to-Wenzel transition would induce the loss of super-hydrophobicity and the so-called self-cleaning effect of the substrates since a Wenzel state would lead to a strong increase of adhesion and friction properties. Owing to the preservation of air cushion in the micro-pits, droplets impacting on closed-cell  ...   ...   ...   ...   ...   ...   ...  instead of transferring into Wenzel state. Proper design of closed-cell micro-structured surfaces can delay the so-called Cassie-to-Wenzel transition and maintain hydrophobicity and water-repellency even under high-speed droplets impact.
