||The leaves of some natural plants show a microstructure that gives them the capacity of being cleaned from any undesired particles on them by rainfall. This project provides a thorough description of the physical laws that lay behind this phenomenon, known as lotus effect. The different existing theories regarding the controversial scientific field of water-repellency are analyzed and compared. The problem of adapting this behavior to artificially roughened surfaces is addressed by providing design criteria for superhydrophobic, water-repellent and self-cleaning surfaces according to the concrete performance desired for them. Furthermore, the production of microstructured surfaces following two different manufacturing techniques is reported.
