Abstract
The present invention is related to a thermostable electroconductive polymer layer comprising an iodine-doped polymer layer based on 1-amino-9,10-anthraquinone having an electrical conductivity in the range of about 10−2 Sm/cm to about 102 Sm/cm. Additionally, the present invention is related to methods for preparing the thermostable electroconductive polymer layer. The method comprises polymerizing 1-amino-9,10-anthraquinone vapors at a reduced pressure in a direct current discharge on a cathode at a temperature in the range of about 150° C. to about 300° C., providing the necessary vapor pressure for a time period in the range of about 5 minutes to about 30 minutes and doping the prepared layer with iodine vapors.
