Abstract

The present invention refers to a method for selectively structuring of a polymer matrix comprising AgNW (silver nano wires) or CNTs (carbon nano tubes) or comprising mixtures of AgNW and CNTs on a flexible plastic substructure or solid glass sheet. The method also includes a suitable etching composition, which allows to proceed the method in a mass production.
