    Abstract: The invention relates to a process for producing a patterned transparent conductive film comprising areas with lower conductivity and areas with higher conductivity, comprising following steps: (a) applying an ink comprising electrically conductive nanoobjects with or without a binder on a substrate, forming a first layer, wherein the amount of conductive nanoobjects is such that the first layer has a low conductivity after drying; (b) drying of the first layer; (c) applying an ink comprising a metallo-organic complex in a predetermined pattern on the first layer; (d) decomposing of the ink applied in step (c), thereby forming a pattern having a higher conductivity on the first layer. The invention further relates to a transparent conductive film, comprising areas with lower conductivity and areas with higher conductivity, wherein the areas with higher conductivity and the areas with lower conductivity comprise nanoobjects and in the areas with higher conductivity, the nanoobjects are fused by metal generated by decomposition of a metallo-organic complex.

    Abstract: Described is a method of preparing a product comprising an amount of surface modified silver nanowires, the method comprising the following steps: preparing or providing a first surface agent compound having one or more functional groups selected from the group consisting of thiol and amine, for attaching the first surface agent compound to the surface of a silver nanowire, preparing or providing an amount of silver nanowires, attaching said first surface agent compound prepared or provided in step (a) to the surface of said silver nanowires prepared or provided in step (b), so that surface modified silver nanowires result, and optionally (d) adding one or more further constituents and/or conducting one or more further steps so that said product results. Also described are a corresponding product, corresponding uses and a method of coating the surface of an article.

    Abstract: The invention relates to a patterned transparent conductive film, comprising areas with higher conductivity and areas with lower conductivity, wherein in the areas with higher conductivity nanoobjects are disposed in a binder matrix such that the nanoobjects are interconnected and thereby form an area with higher conductivity and wherein in the areas with lower conductivity the nanoobjects are structurally intact and are coated with an insulating coating material. The invention further relates to a process for producing such a patterned transparent conductive film comprising areas with lower conductivity and areas with higher conductivity, comprising following steps: (a) applying an ink comprising electrically conductive nanoobjects and a binder on a substrate, forming a first layer, wherein the amount of conductive nanoobjects is such that the first layer is conductive after drying; (b) drying of the first layer; (c) applying a mixture comprising an insulating coating material or a precursor of an insulating coating material on that parts of the first layer which shall form the areas with lower conductivity, wherein the insulating coating material or the precursors form an insulating coating around the electrically conductive nanowires; (d) drying of the coated substrate.
