The method for the preparation of self-cleaning surfaces having protrusions and recesses, wherein the distance between said protrusions is in a range of from 0.1 to 200 µm and the height of said protrusions is in a range of from 0.1 to 100 µm is performed by applying a solution, dispersion or emulsion containing a hydrophobic material which forms a self-cleaning surface by self-organization when the solvent is evaporated, followed by drying, wherein the material applied can be removed with detergents.
Cette invention concerne un procédé de réalisation de surfaces autonettoyantes présentant des bosses et des creux, la hauteur des bosses étant comprise entre 0,1 et 200 mu m et la profondeur des creux étant comprise entre 0,1 et 100 mu m. Selon ce procédé, une solution, dispersion ou émulsion, contenant un agent hydrophobe qui, lors de l'évaporation du solvant, forme une surface autonettoyante autoadaptative, est appliquée et finalement séchée. Le matériau appliqué peut être retiré au moyen de détergents.
