    摘要: A method of processing bundles of carbon nanotubes (CNTs). Bundles of CNTs are put into a solution and unbundled using sonication and one or more surfactants that break apart and disperse at least some of the bundles into the solution such that it contains individual semiconducting CNTs, individual metallic CNTs, and remaining CNT bundles. The individual CNTs are separated from each other using agarose bead column separation using sodium dodecyl sulfate as a surfactant. Remaining CNT bundles are then separated out by performing density-gradient ultracentrifugation.

    摘要: A process of sorting metallic single wall carbon nanotubes (SWNTs) from semiconducting types by disposing the SWNTs in a dilute fluid, exposing the SWNTs to a dipole-inducing magnetic field which induces magnetic dipoles in the SWNTs so that a strength of a dipole depends on a conductivity of the SWNT containing the dipole, orienting the metallic SWNTs, and exposing the SWNTs to a magnetic field with a spatial gradient so that the oriented metallic SWNTs drift in the magnetic field gradient and thereby becomes spatially separated from the semiconducting SWNTs. An apparatus for the process of sorting SWNTs is disclosed.

    摘要: Disclosed is a novel method for the selective molecular conversion of raw material carbon nanotubes containing a mixture of metallic carbon nanotubes and semiconductive carbon nanotubes in a manner that is based on the electrical properties or diameter of the carbon nanotubes.The present invention causes a photoreaction of raw material carbon nanotubes containing a mixture of metallic carbon nanotubes and semiconductive carbon nanotubes with a disulfide or a sulfide of the following formula (I) or (II) (wherein R1 and R2 each independently represent a hydrocarbon group that may have a substituent) in an organic solvent that contains the raw material carbon nanotubes and the disulfide of the formula (I) or the sulfide of the formula (II), so as to selectively functionalize the metallic carbon nanotubes, or functionalize the carbon nanotubes diameter selectively.
