Abstract
The invention relates to a dispersion which contains particles of at least one intrinsically conductive polymer, wherein the particle size is on average (weight) less than 1 μm, and which is characterized in that the dispersant is a liquid at room temperature, and a layer, film or sheet formed from this dispersion has a conductivity of >100 S/cm after removal of the dispersant. The invention also relates to a process for the preparation of this dispersion.
