Title (EN) SELECTIVE PLACEMENT OF CARBON NANOTUBES THROUGH FUNCTIONALIZATION
(FR) PLACEMENT SELECTIF DE NANOTUBES DE CARBONE PAR FONCTIONNALISATION
Abstract:
(EN) The present invention provides a method for selectively placing carbon nanotubes on a substrate surface by using functionalized carbon nanotubes having an organic compound that is covalently bonded to such carbon nanotubes. The organic compound comprises at least two functional groups, the first of which is capable of forming covalent bonds with carbon nanotubes, and the second of which is capable of selectively bonding metal oxides. Such functionalized carbon nanotubes are contacted with a substrate surface that has at least one portion containing a metal oxide. The second functional group of the organic compound selectively bonds to the metal oxide, so as to selectively place the functionalized carbon nanotubes on the at least one portion of the substrate surface that comprises the metal oxide.
(FR) La présente invention concerne un procédé destiné à placer sélectivement des nanotubes de carbone sur une surface de substrat en utilisant des nanotubes de carbone fonctionnalisés ayant un composé organique qui est lié de manière covalente à de tels nanotubes de carbone. Le composé organique comprend au moins deux groupes fonctionnels, le premier étant capable de former des liaisons covalentes avec des nanotubes de carbone, et le second étant capable de lier de manière sélective des oxydes de métaux. De tels nanotubes de carbone fonctionnalisés sont mis en contact avec une surface de substrat qui possède au moins une partie contenant un oxyde de métal. Le second groupe fonctionnel du composé organique se lie de manière sélective à l’oxyde de métal, afin de placer de manière sélective les nanotubes de carbone fonctionnalisés sur la ou les parties de la surface de substrat comprenant de l'oxyde de métal.
