The present invention relates to a process for the production of a layer composition (10) with an electrically conductive layer (11), comprising the process steps:
a) provision of a substrate (12) with a substrate surface (13);
b) formation of a polymer layer (14) comprising an electrically conductive polymer (15) on at least a part of the substrate surface (13);
c) application of a liquid stabilizer phase, comprising a stabilizer and a liquid phase, to the polymer layer (14) from process step b), wherein the stabilizer phase comprises less than 0.2 wt.%, based on the stabilizer phase, of the electrically conductive polymer,
wherein the stabilizer (7) is an aromatic compound with at least two OH groups and one further functional group with a hetero atom which differs from carbon, wherein the further functional group is selected from the group consisting of an ester group, a carboxyl group and an amide group.
本发明涉及一种生产具有导电层(11)的层组合物(10)的工艺,包括以下工艺步骤:
