NON-WETTABLE SURFACES

摘要

The invention relates to an object comprising a surface with filaments, whose length ranges between 30 and 6000 µm, which have a ratio of diameter to length of between 1 : 10 and 1 : 20 and which are bonded to the surface by at least one end face. According to the invention, the distance between two filaments on the surface is such that the ratio of said distance to the length of the filaments is between 1 : 3 and 1 : 10, the filaments have an elasticity of between 10⁴ bis 10¹⁰ N/m²and the surface of the filaments is hydrophobic in such a way that the contact angle between a filament and water is greater than 100°.
