...onomer, under the trade name Basotronic PYR, from BASF AG, Ludwigshafen . Polyethylene dioxythiophene (PEDT) is available as both a monomer and as a polymer. The monomer ethylene dioxythiophene (EDT) is available under the trade name Baytron M, the polymer under the trade name Baytron P as a water-dispersable polymer complex between PEDT and polystyrene sulfonic acid (PSS). The company H.C. Starck GmbH in Leverkusen, a subsidiary of Bayer MaterialScience AG, is the manufacturer and supplier of t...

...lly contain an electrode made of an aluminium or tantalum foil. Manganese dioxide is conventionally used as the counter-electrode. Alternatively the conducting polyethylene dioxythiophene (PEDT) from H. C Starck (Baytron) is already used as the counter-electrode in tantalum or aluminium elcos. Compared to manganese dioxide it can be more easily applied and has a significantly higher conductivity. Thus the development of a new more efficient condenser generation with an improved high-frequency re...

It consists of Makrofol (PC) and Bayfol (PC+PBT) films, a transparent electrode made from the electrically conducting polymer Baytron poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), Noriphan HTR screen-printing inks from Pröll AG, which are based on the heat-resistant polycarbonate Apec HT, and the PC+ABS blend Bayblend. The inverter on the back side was encapsulated in polyurethane. “As a solution pro...

...t of the materials and construction (frameless modules – cost savings) and the possibility in the long term of replacing cost-intensive ITO (indium tin oxide) electrodes by highly conductive polymers (see the developments by H.C. Starck with Baytron P and by Ormecon or Panipol with polyaniline). Service Life of 2000 Solar Hours Polymer solar cells consist of a multilayer structure on film or glass, based on two electrodes (indium tin oxide: ITO, aluminum: Al) and two functional polymer layers ...

...re opening up new technical possibilities and tapping into new application fields. Previous grades of polymers were no match for ITO when it came to conductivity. However, one highly conductive form of polyethylene dioxythiophene (Pedot, trade name: Baytron) has conductivity values of up to of 500 S/cm. This is still a good order of magnitude lower than the conductivity of ITO, but is sufficient to allow production of organic LED-based lights that are totally free of ITO (Fig. 4). Thus, combinin...

Each is made of a blank Makrolon CD/DVD media imprinted on the back, coated with pushbuttons made of electrically conductive Baytron P polymers by H.C. Starck. Touching the cockpits’ mechanical operating elements feels warm, soft and therefore very pleasing. This comfort effect is caused by a polyurethane Soft Feel coating, based on the high-quality, watery varnishing raw materials o...

...d for making capacitors. Polymeric substitutes for ITO, however, need to be highly conducting and highly transparent. The development of highly conducting grades using the example of polyethylene dioxythiophene (PEDOT, trade name Clevios, formerly Baytron) shows that, comparable to Moore's Law, conductivity is steadily increasing (Fig. 8). Conductivity values of up to 500S/cm have so far been achieved. Although this is still about one order of magnitude lower than that of ITO, it has already...
