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.
