CONTEXT

Carbon aerogels are highly porous structures which show a very low apparent density. They are generally produced by "templating" methods where a 3D structure is used as a template impregnated by carbon/carbon precursor to give the required geometry. From carbon nanotubes solutions, it is possible to prepare monolithic aerogels formed of an entangled network of carbon nanotubes. Such materials may have applications in composites, supercapacitors, catalysis or decontamination (oil adsorption, filtration, etc...)
