The invention relates to a structured surface with ultraphobic properties. Said surface as a surface topography in which the value of the integral of a function S: S(log f)=a(f)·f, which gives a relationship between the spatial frequencies f of the individual Fourier components and their amplitudes a(f) is at least 0.5 between the integration limits log (f 1 /μm −1 )=−3 and log (f 2 /μm −1 )=3. The surface consists of a hydrophobic or oleophobic material or is coated with a hydrophobic or oleophobic material. |
