NON-WETTABLE SURFACES

摘要

An object having a surface, which comprises filaments having a length of 30 to 6000 µm, a ratio of the diameter to the length of between 1:10 and 1:20 and with at least one front are bound to the surface, the distance between two filaments on the surface being such that the ratio of the distance to the length of the filaments is between 1:3 and 1:10, the elasticity of the filaments is between 104 and 1010 N/m2, the surface of the filaments is at least partially hydrophobic such that the contact angle between a filament and water is greater than 100°, characterized in that the filaments are structurally or chemically anisotropic.
