Title
(EN) SEEDLESS PARTICLES WITH CARBON ALLOTROPES
(FR) PARTICULES SANS GERMES COMPORTANT DES ALLOTROPES DU CARBONE
Abstract
(EN)
Carbon materials having carbon aggregates, where the aggregates include carbon nanoparticles and no seed particles, are disclosed. In various embodiments, the nanoparticles include graphene, optionally with multi-walled spherical fullerenes and/or another carbon allotrope. In various embodiments, the nanoparticles and aggregates have different combinations of: a Raman spectrum with a 2D-mode peak and a G-mode peak, and a 2D/G intensity ratio greater than 0.5, a low concentration of elemental impurities, a high Brunauer-Emmett and Teller (BET) surface area, a large particle size, and/or a high electrical conductivity. Methods are provided to produce the carbon materials.

L'invention concerne des matériaux carbonés comportant des agrégats de carbone, les agrégats comprenant des nanoparticules de carbone et pas de particules servant de germes. Dans divers modes de réalisation, les nanoparticules comprennent du graphène, éventuellement avec des fullerènes sphériques à parois multiples et/ou un autre allotrope du carbone. Dans divers modes de réalisation, les nanoparticules et les agrégats présentent différentes combinaisons constituées : d'un spectre Raman présentant un pic en mode 2D et un pic en mode G, et un rapport d'intensité 2D/G supérieur à 0,5, d'une faible concentration en impuretés élémentaires, d'une surface de Brunauer-Emmett-Teller (BET) élevée, d'une grande taille de particules et/ou d'une conductivité électrique élevée. L'invention concerne également des procédés de production des matériaux carbonés.
