Abstract:
A surface for an article has an artificially producible base structure (10). The structure (12) has or develops a capillary effect at which the quotient from capillary work (K) and adhesion work (A) is larger 1. The capillary structures and their capillaries have a negative capillary rise such that liquid is forced from the capillaries, allowing for a self-cleaning effect.
