    摘要: The subject of the present invention is a process for synthesizing nanotubes, especially carbon nanotubes, by decomposition of a gas source, at a temperature ranging from 400 to 1200 °C in a reactor, by bringing it into contact with at least one (one or more) multivalent transition metals, the transition metal(s) being supported on a support having a specific surface area determined by the BET method of greater than 50 m2/g, especially within the range from 70 m2/g to 400 m2/g. The support according to the invention is especially an inorganic support, for example an alumina having a multimodal porosity. The subject of the invention is also the nanotubes thus obtained and their use for improving the mechanical and/or electrical and/or thermal properties of materials, especially polymeric materials.

    摘要: The invention relates to a simple and economic method for treatment of carbon nanotubes, in particular, for the modification of the surface thereof by functionalisation for improving the compatibility thereof with polar media, such as certain polymers, resins or solvents. The invention further relates to nanotubes treated thus and the use thereof in the electronic, electromechanical and mechanical fields in which the above represent an advantageous replacement for untreated carbon nanotubes.
