Lotus effect

The lotus effect, also called the lotus effect, denotes the low wettability of a surface, as can be observed in the lotus plant. The microstructured leaf top of this plant can not be wetted by water and many other aqueous fluids, forming droplets that do not adhere to the surface. Also adhering to common surfaces solids such as paint show reduced grip and can be easily washed away. The lotus effect thus describes the self-cleaning of hierarchically structured surfaces in the interaction of low wettability and reduced interpersonal skills, Other plants, such as the nasturtium, cabbage, reed, columbine, tulip, lady's mantle and banana show this effect.

Self-cleaning surfaces are of increasing technical and economic importance.
