Abstract

Divers modes de réalisation procurent des matériaux et des procédés de formation dun produit de graphène par chauffage à induction sous vide de graphite expansible. Le produit de graphène peut comprendre des nanofeuilles de graphène avec une pureté élevée et une épaisseur uniforme. Les nanofeuilles de graphite peuvent contenir du carbone en une quantité supérieure à environ 99 % en poids. Les nanofeuilles de graphène peuvent être exfoliées ou dispersées au sein dune matrice de polymère semi-conducteur pour former un composite qui contient du graphène.
