Abstract

Described are methods for surface modification of an object (10) in order to increase the adhesive power of the object, wherein the surface (11) is subjected to structuring so that a multitude of projections (12) are formed, each comprising a foot part and a head part, wherein the head part comprises a front surface (13) which faces away from the surface, wherein each projection (12) is made in a size such that all front surfaces (13) project to the same vertical height above the surface (11), and form an adherent contact surface (14) which is interrupted by mutual spacing between the front surfaces (13).
