Abstract
A coated article, which has (i) at least one electrically non-conductive base layer, (ii) at least one layer of copper and/or a copper alloy, and (iii) a layer which contains at least one electrically conductive polymer. The article is characterized in that the copper or copper alloy layer (ii) is positioned between the base layer (i) and the layer (iii) containing the conductive polymer.
Claims14
A coated article comprising:
- (i) at least one electrically non-conductive base layer,
- (ii) at least one layer of at least one of copper and a copper alloy applied on a surface of the base layer (i), and
- (iii) a layer which contains at least one intrinsically conductive polymer,
- characterized in that the copper or copper alloy layer (ii) is positioned between the base layer (i) and the layer (iii) containing the conductive polymer, wherein the layer (iii) further comprises at least one electrically non-conductive polymer in addition to the at least one intrinsically conductive polymer, wherein the layer (iii) contains at least one complexing agent capable of complexing copper in addition to the at least one electrically non-conductive polymer, wherein the complexing agent is selected from the group consisting of benzimidazoles, imidazoles, benzotriazoles, thiourea, imidazole-2-thiones and mixtures thereof.
