Preparing individual carbon nanotube aerogel, useful e.g. to prepare composite materials, comprises reducing carbon nanotubes, exposing polyelectrolyte salt to polar solvent, freezing solution of nanotubes and sublimation of solvent

摘要

Process for preparing an individual carbon nanotube aerogel, comprises (a) reduction of carbon nanotubes by an alkaline metal for producing a carbon nanotube polyelectrolyte salt, (b) exposing polyelectrolyte salt of carbon nanotubes to an aprotic polar solvent for producing a solution of reduced individual carbon nanotubes, (c) freezing the solution of individual nanotubes, and (d) sublimation of the solvent, in an inert atmosphere. Independent claims are included for: (1) the individual carbon nanotube aerogel obtained by the process; and (2) a use of aerogel for preparation of composite materials.
