Abstract: A method for producing and/or processing polymer/carbon nanotube mixtures in powder form comprises the step of grinding a mixture comprising carbon nanotubes and polymer particles. The grinding is carried out in the presence of from ?0 weight-% to ?15 weight-%, expressed in terms of the total weight of the mixture, of a liquid phase which does not dissolve the polymer particles and at a temperature below the melting point of the powder particles. The energy input during the grinding is preferably low. A preferred polymer is PVDF. The invention furthermore relates to polymer/carbon nanotube mixtures which can be obtained by a method according to the invention, and to the use of such polymer/carbon nanotube mixtures for the production of electrodes.
