The invention relates to a method for preparing aerogels of individualised carbon nanotubes and to the applications thereof, in particular in the production of composite aerogels and electrochemical compounds. The method of the invention is characterised in that it comprises the following steps carried out in an inert atmosphere: (a) reducing the carbon nanotubes using an alkaline metal in order to obtain a polyelectrolyte salt of carbon nanotubes; (b) exposing said polyelectrolyte salt of carbon nanotubes to an aprotic polar solvent in order to obtain a solution of individualised, reduced carbon nanotubes; (c) freezing said solution of individualised nanotubes; and (d) sublimating the solvent. The invention particularly relates to aerogels of individualised carbon nanotubes obtained by said method, and to the uses of said aerogels. |
