The present invention relates to novel carbon nanoparticles, especially to carbon nanoparticles which comprise or consist of carbon nanotubes and have been modified by means of acyl groups, to a novel process with which these modified carbon nanoparticles, especially carbon nanoparticles comprising or consisting of carbon nanotubes, are obtainable, and to the use of the modified carbon nanoparticles, especially carbon nanoparticles comprising or consisting of carbon nanotubes.

Modified carbon nanoparticles, method for the production thereof and use thereof

A method for separating metallic carbon nanotubes and semi-conducting carbon nanotubes includes providing a suspension containing a plurality of individual metallic carbon nanotubes and semi-conducting carbon nanotubes in a liquid, for which the dielectric constant &#x3b5;meets the requirement: &#x3b5;&#x3e;&#x3b5;&#x3e;&#x3b5;, wherein &#x3b5;is the dieletric constant of the metallic carbon nanotubes and &#x3b5;is the dielectric constant of the semi-conducting carbon nanotubes. A a non-homogeneous electric alternating field is applied to the suspension to create spatially separate species of the metallic carbon nanotubes and the semi-conducting carbon nanotubes. At least one of the separate species is then removed.
