Method, arrangement and use of an arrangement for separating metallic carbon nanotubes from semi-conducting carbon nanotubes

Abstract

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 εL meets the requirement: εM>εL>εH, wherein εM is the dieletric constant of the metallic carbon nanotubes and εH 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.
