CA 2207282

Graphitic nanotubes, which includes tubular fullerenes (commonly called "buckytubes") and fibrils, which are functionalized by chemical substitution or by adsorption of functional moieties. More specifically the invention relates to graphitic nanotubes which are uniformly or non-uniformly substituted with chemical moieties or upon which certain cyclic compounds are adsorbed and to complex structures comprised of such functionalized fibrils linked to one another. The invention also relates to methods of introducing functional groups onto the surface of such fibrils.

On décrit des nanotubes graphitiques, qui comprennent des fullerènes tubulaires (des "buckytubes") et des fibrilles, rendus fonctionnels par substitution chimique ou par adsorption de fractions fonctionnelles. Plus précisement, on décrit des nanotubes graphitiques qui présentent une substitution uniforme ou non, avec des fractions chimiques ou sur lesquels sont adsorbés certains composés cyliques, et on décrit des structures complexes comprenant ces fibrilles rendues fonctionnelles et liées les unes aux autres. On décrit enfin des procédés permettant d'introduire des groupes fonctionnels à la surface de telles fibrilles.
