NOVELTY - A superhydrophobic polymer or metal surface is manufactured by forming a polymeric layer on a base substrate and having a bottom surface attached to the substrate base, and upper surface. The polymeric material in the layer is structured at two different size scales. The polymeric material is structured at a third size scale by forming indentations on the upper surface. An average distance between adjacent indentations is 20-200 mu m, thus obtaining a water-repellent surface comprising fractal-like texturing at three different size scales.    USE - Method is for manufacture of superhydrophobic polymer or metal surface used in an article, e.g. water-repellant textile or its item made, non-wetted membranes, antenna coatings, parts of fuel cells, parts of batteries, and parts of desalination devices.    ADVANTAGE - The method provides a simple and inexpensive method of producing superhydrophobic surfaces.    DETAILED DESCRIPTION - Manufacture of superhydrophobic polymer or metal surface involves forming a polymeric layer on a base substrate and having a bottom surface attached to the substrate base, and upper surface. The polymeric material in the layer is structured at two different size scales. The lower scale is a nanoscale (first size scale). The larger (second) scale comprises 0.5-50 mu m. The polymeric material is structured at a third size scale by forming indentations on the upper surface. An average distance between adjacent indentations is 20-200 mu m, thus obtaining a water-repellent surface comprising fractal-like texturing at three different size scales. If a metal surface is wished to obtain, a metal layer is deposited on the upper surface. An INDEPENDENT CLAIM is included for an article, e.g. water-repellant textile or its item made, non-wetted membranes, antenna coatings, parts of fuel cells, parts of batteries, and parts of desalination devices, comprising a polymer layer exhibiting a superhydrophobic surface structured at three different size scale in a fractal-like manner, comprising a structuring at a first size scale of 0.1-2 mu m, structuring at a second size scale of 2-20 mu m, and structuring at a third size scale of 20-200 mu m.
