Definitions
- the invention is based on known methods for producing structures of electrically conductive material using printing methods.
- the invention relates to a method with which it is possible to deposit nanofibers targeted with high local precision on any surface. This is made possible by a particularly adapted process of so-called electrospinning in conjunction with a material suitable for this, from which the electrically conductive structures are formed by the structures consist of conductive particles or subjected to a post-treatment to generate conductivity.
- the optical transparency and gloss are technically demanding in this context. They can only be reached via three routes. Either the substrate material itself is deliberately made conductive without impairing its mechanical and optical properties, or a material is used which is conductive, but visually optically imperceptible to humans and can be easily applied selectively to the surface of the substrate, or a conductive material is used which, although not transparent itself, can be applied to the surface by means of a suitable process such that the resulting structure is suitable for human beings Generally without the aid of optical aids is imperceptible. This does not affect the gloss and transparency properties of the substrate.
- submicron structures i.e., with a line width of ⁇ 1 ⁇ m are particularly desirable.
- a method by which structures smaller than 1 ⁇ m can alternatively be represented on polymer surfaces is the so-called hot embossing.

- Disadvantage of hot stamping is the restriction of the structural shape to the shape of the embossing stamp or embossing roll used in each case. A free design of the structure is not possible hereby.
- Electrospun fibers are only obtained in the form of large, disordered fiber mats. Ordered fibers have so far only been possible by spinning on a rotating roller [Biomacromolecules, 2002, 3, 232]. It is further known that conductive fibers in principle can be spun by "electrospinning.” A corresponding conductive material for such use utilizing the conductivity of carbon nanotubes is also known [Langmuir, 2004, 20 (22), 9852].
- US2005-0287366 discloses a method and material that can be used to produce conductive fibers.

- substrate and capillary can be moved.
- the substrate is moved under the capillary.

- the specified material is desirably on the substrate and may be post-treated as needed to increase conductivity.
- This post-treatment includes the entry of energy into the generated structures.
- the polymer particles present in suspension in the solvent are e.g. fused together by heating the suspension on the substrate while the solvent evaporates at least partially.

Thereafter, the air of the drying oven in which the sample was 9, replaced by argon and within 30 minutes, the temperature increased to 250 0 C. Argon was then replaced by hydrogen. Under this hydrogen atmosphere, the temperature was again held at 250 ° C. for 60 minutes. The mixture was then switched back to argon as gas for the drying oven and the sample 9 was heated to a temperature of 800 0 C within two hours. Finally, the argon was added to the argon hexane for seven minutes and finally the sample 9 was cooled back to room temperature under argon.

- the result was a conductive line based essentially on carbon. Upon contact of two points of the line at a distance of 190 ⁇ m, a resistance of 1.3 kOhm was measured.
- the line had a linewidth of about 130 nm.
