The invention provides methods for metallizing polymer layer systems and corresponding polymer layer systems. In accordance with one aspect, the method comprises the following steps: forming a layer stack (1, 2, 3; 1, 2, 3'; 1, 2, 3"; 1a, 2a, 3a; 1c, 2c, 3c, 3d) with a polymer substrate (1; 1a; 1c), a metal film (3; 3'; 3"; 3a; 3c, 3d) and an interposed polymer membrane (2; 2a; 2c); forming one or more structure regions (6; 6"'; 6""; 6a; 6c, 6d) in the metal film (3; 3'; 3"; 3a; 3c, 3d) by means of a first laser irradiation step (L2; L2'); and removing the metal film (3; 3'; 3"; 3a; 3c, 3d) from a region (6') which is complementary to the structure region(s) (6; 6"'; 6""; 6a; 6c, 6d). In accordance with a further aspect, the method comprises the following steps: forming a layer stack (1, 2, 3'; 1, 2, 3") with a polymer substrate (1), a structured metal film (3'; 3"), at least regions of which are provided with perforations (4; 4'), and an interposed polymer membrane (2); wherein, once the layer stack (1, 2, 3'; 1, 2, 3") has been formed, a laser irradiation step (L1) is performed through a surface (O1) of the polymer substrate (1) which is remote from the polymer membrane (2), as a result of which a welded joint is produced between the polymer substrate (1) and the polymer membrane (2); and wherein the polymer membrane (2) flows into the perforations (4; 4') during the second laser irradiation step (L1) and forms webs (2a; 2a'). |
