Abstract:
The present invention relates to the production of a layer structure, comprising the following process steps: i) coating a substrate with a composition at least comprising silver nanowires and a solvent; ii) at least partial removal of the solvent, thereby obtaining a substrate that is coated with an electrically conductive layer, the electrically conductive layer at least comprising the silver nanowires; iii) bringing into contact selected areas of the electrically conductive layer with an etching composition, thereby reducing the conductivity of the electrically conductive layer in these selected areas, wherein the etching composition comprises an organic compound capable of releasing chlorine, bromine or iodine, a compound containing hypochloride, a compound containing hypo-bromide or a mixture of at least two of these compounds. The invention also relates to a layer structure obtainable by this method, a layer structure, the use of a layer structure, an electronic component and the use of an organic compound.
