Definitions
- the invention relates to conductive polymer solutions which can be used for the production of organic electronic components.
- printable inks are being developed in which the conductive polymers are readily soluble, although due to their rheological properties such as viscosity, adhesion and wetting behavior, these substances are only soluble within narrow limits and therefore do not yet meet the requirements for structure and Layer quality can be provided.
- Polymer solutions which are made conductive by adding carbon black (carbon black) or graphite.
- carbon black carbon black
- graphite A mixture of soot and graphite particles is also known. It describes how these mixtures can be used advantageously for the construction of organic circuits.
- Other materials that improve the functionality of the layers, for example Pani or Pedo, can of course also be added to these mixtures.
- the object of the present invention is to modify the particles of the carbon black / graphite particles in the polymer solutions in such a way that solutions result which do not cause damage to the components or to the printing presses.
- the invention relates to the use of a polymer solution filled with carbon black / graphite, in which the carbon black / graphite particles are essentially in the form of microplates, for the production of electronic components.
- organic electronic components e.g. organic transistors and circuits made of them, organic diodes, organically based capacitors, organic photovoltaic cells, organic sensors and actuators, as well as combinations thereof.
- microplates are used which are in a centerless form.
- polymer solutions which have a solids content of 15 to 60% by weight, in particular 20 to 45% by weight, particularly preferably 34.5 to 41% by weight.
- the viscosity of the solutions used can vary widely, both resins (viscosities between 20,000- 40,000 mPa.s) and liquids (viscosities between 800-3600 mPa.s) are used, the term "solution" only referring to the fact that one component is present in solution in another.
- the polymer solutions in question here can be, for example, liquid, gel-like, solid or resinous, the addition of the carbon black / graphite particles again having an influence on the viscosity.
- the choice of solvent depends on the printing and / or drying properties that are to be achieved.
- the polymer solutions with micro-platelets have proven their suitability for use in low-cost microelectronics.
- the advantage of polymer solutions is that, with satisfactory electrical functions in the microelectronic component, they combine good processability, especially in terms of pressure behavior, with a wide variability in the concentration of carbon black / graphite particles.
- Carbon-black / graphite-filled polymer solutions are preferably used, which were developed by the company Acheson Colloids Company (ww. Achesonindustries. Com) for medical electrodes, battery covers, rubber resins and the like.
- Electrodeag ® PF-407A a well-known screen printing compound that was not designed for use in microelectronics, was used for tampon printing of vias and gate electrodes.
- the material was stable and functional in individual polmer Field effect transistors up to ring oscillator circuits.
