Methods of oxidizing multiwalled carbon nanotubes are pro-vided. The multiwalled carbon nanotubes are oxidized by contacting the car-bon nanotubes with gas-phase oxidizing agents such as CO2, O2, steam, N2O, NO, NO2, O3, and ClO2. Near critical and supercritical water can also be used as oxidizing agents. The multiwalled carbon nanotubes oxidized according to methods of the invention can be used to prepare rigid porous structures which can be utilized to form electrodes for fabrication of improved electrochemical capacitors.

Cette invention a trait à des techniques d'oxydation de nanotubes de carbone à parois multiples. On oxyde ces derniers en les faisant entrer en contact avec des agents oxydants en phase gazeuse tels que du CO2, de l'O2, de la vapeur, du N2O, du NO, du NO2, de l'O3 et du ClO2. Il est également possible d'utiliser comme agents oxydants de l'eau quasi critique et supercritique. Il est possible d'utiliser les nanotubes de carbone à parois multiples oxydés selon les techniques de l'invention pour préparer des structures poreuses rigides susceptibles d'être employées pour constituer des électrodes aux fins de la production de condensateurs électrochimiques améliorés.
