Non-wettable Surfaces

An object having a surface that has: filaments having a length of from 30 to 6000 [mu]m, a diameter to length ratio of from 1:10 to 1:20, and are bound to the surface with at least one front face thereof; wherein the distance between two neighboring filaments on the surface is such that the ratio of such distance to the length of the filaments is from 1:3 to 1:10; the filaments have an elasticity of from 104 to 1010 N/m2; the surface of the filament is at least partially hydrophobic, so that the contact angle between a filament and water is greater than 100 DEG , characterized in that the filaments are structurally or chemically anisotropic.
