Method for producing an electrically conductive carbon conductor with carbon structural forms

Abstract

The present invention relates to a method for producing an electrical carbon conductor from carbon structural forms, which are in particular allotropic modifications of the carbon, in particular graphite, pyrolytic graphite, graphene and/or carbon nanotubes, and precursor compounds of graphene, such as graphene oxide, for example, which, in order to increase the electrical conductivity of the electrical carbon conductor, are doped with an additive for doping the carbon structural forms, in particular aluminum fluoride and/or aluminum chlorofluoride and/or perfluorinated polymeric sulfonic acid, characterized by the steps: producing a liquid dispersion from undoped carbon structural forms and a solvent, adding the additive to the dispersion and mixing the dispersion, producing a conductor strand in fiber or film form to form the carbon conductor, in particular by wet-spinning the dispersion or by depositing the dispersion on a carrier material, and by removing the dispersion fluid from the conductor strand as a liquid phase, which is achieved in particular by drying, vacuum and heat treatment.
