Abstract
The present invention relates to a conductive polymer or organic metal which is characterized in that nanoscopic particles formed from same with a particle size of less than 100 nm have an anisotropic morphology which is not spherical and has a length-to-diameter (“L/D”) ratio greater than 1.2. The invention also relates to a process for the preparation of such polymers and their use in the preparation of shaped parts, self-supporting foils or coatings with electrical conductivity, in particular on anisotropic substrates or in anisotropic media and fields.
Claims8
A conductive polymer comprising nanoscopic primary particles with a particle-size of less than 100 nm which have an anisotropic morphology which is not spherical and has a length-to-diameter (“L/D”) ratio greater than 1.2, wherein the conductive polymer can be dispersed with a dispersant to form a dispersion and the conductive polymer being further characterized by a layer, foil or sheet formed from the dispersion having a conductivity of >100 S/cm after removal of the dispersant.
A method of using a dispersion comprising:
- providing a dispersion comprising a conductive polymer, the conductive polymer comprising nanoscopic primary particles with a particle-size of less than 100 nm which have an anisotropic morphology which is not spherical and having a length-to-diameter (“L/D”) ratio greater than 1.2, the dispersion being further characterized by a layer, foil or sheet formed from the dispersion having a conductivity of >100 S/cm after removal of the dispersant;
- and
- applying the dispersion to at least one of, a shaped part, self-supporting foil or coating with electrical conductivity.
