This invention relates to rigid porous carbon structures and to methods of making same. The rigid porous structures have a high surface area which are substantially free of micropores. Methods for improving the rigidity of the carbon structures include causing the nanofibers to form bonds or become glued with other nanofibers at the fiber intersections. The bonding can be induced by chemical modification of the surface of the nanofibers to promote bonding, by adding "gluing" agents and/or by pyrolyzing the nanofibers to cause fusion or bonding at the interconnect points.

La présente invention porte sur des structures de carbone poreuses et rigides, ainsi que sur leurs procédés de fabrication. Lesdites structures poreuses et rigides ont une surface très active pratiquement exempte de micropores. Pour améliorer la rigidité des structures de carbone, on fait en sorte, notamment, que les nanofibres forment des liaisons ou se collent les unes aux autres à leurs intersections. La liaison peut être provoqueée par modification chimique de la surface des nanofibres en vue de favoriser ladite liaison, par l'adjonction d'agents " collants" et/ou par l'action consistant à effectuer une pyrolyse des nanofibres afin de provoquer leur fusion ou leur liaison aux points d'interconnexion.
