  • Method for preparing a suspension containing carbon nanotubes and stable suspension obtained in this way
    Patent number: 10173189
    Abstract: The present invention concerns a method for preparing a suspension of carbon nanotubes in an aqueous solution comprising the following successive steps consisting of subjecting an aqueous solution containing carbon nanotubes and a surfactant to at least one cycle of freezing in liquid nitrogen and thawing; and subjecting said thawed solution to an ultrasound treatment. The present invention also concerns a suspension of carbon nanotubes, and in particular a suspension of long carbon nanotubes, that can be prepared by such a method.
    Type: Grant

  • Growth of carbon nanotubes on carbon or metal substrates
    Patent number: 8551618
    Abstract: The invention relates to the growth of carbon nanotubes on a substrate, in particular a carbon or metal substrate on which the growth of such nanotubes is usually difficult. Accordingly, the invention includes a first phase that comprises depositing a ceramic sub-layer, followed by a second phase that comprises depositing carbon nanotubes on said sub-layer in a single step and in a single and same growth reactor. The growth can advantageously be carried out by chemical vapor deposition.

  • MATERIAL INCLUDING NANOTUBES OR NANOWIRES GRAFTED IN A MATRIX, METHOD FOR PREPARING SAME AND USES THEREOF
    Publication number: 20130108865
    Abstract: The present invention relates to a material comprising (i) nanotubes or nanowires aligned with each other in a vertical matrix and (ii) a matrix arranged between the nanotubes or the nanowires, at least one organic polymer being covalently grafted to at least two of said nanotubes or to at least two of said nanowires. The present invention also relates to a method for preparing such a material or to its uses.
