Abstract

The present invention relates to a method for separating semi-conducting and metallic single-walled carbon nanotubes from each other and, if present, from other carbonaceous material, or for separating semi-conducting single-walled carbon nanotubes from other carbonaceous material, via centrifugation performed by a temperature of> 25°C using a solution of a polytungstate as sepa­ ration medium; to semi-conducting single-walled carbon nanotubes obtainable by this method; and to the use of these semi-conducting single-walled carbon nanotubes e.g. in electronic devices, optical devices, optoelectronic devices, energy storage devices and the like.
