Abstract: A plastic substrate having a porous layer is disclosed. In an embodiment, the porous layer is formed at least partially from a material of the plastic substrate and has pores. The proportion by volume of pores is greater in a first region of the porous layer than in a second region of the porous layer. The second region follows the first region, as seen proceeding from the plastic substrate. The porous layer can be produced by a plasma process that simultaneously effects structuring of the plastic substrate by ion bombardment and coating of the plastic substrate.

Abstract: A process is described for modification of a surface of a substrate by ion bombardment, in which the ions are produced by means of a magnetic field-assisted glow discharge in a process gas. The magnetic field-assisted glow discharge is produced by means of a magnetron having an electrode and at least one magnet for production of the magnetic field. The process gas has at least one electronegative constituent, such that negative ions are produced in the magnetic field-assisted glow discharge, and the negative ions which are produced at the surface of the electrode are accelerated in the direction of the substrate by an electrical voltage applied to the electrode.
