Title (EN) SYNTHESIS OF GRAPHENE SHEETS AND NANOPARTICLE COMPOSITES COMPRISING SAME
(FR) SYNTHÈSE DE FEUILLETS DE GRAPHÈNE ET COMPOSITES NANOPARTICULAIRES EN COMPRENANT
Abstract: front page image
(EN)A method for producing isolatable and dispersible graphene sheets, wherein the graphene sheets may be tailored to be soluble in aqueous, non-aqueous or semi-aqueous solutions. The water soluble graphene sheets may be used to produce a metal nanoparticle-graphene composite having a specific surface area that is 20 times greater than aggregated graphene sheets. Graphene sheets that are soluble in organic solvents may be used to make graphene-polymer composites.
(FR)La présente invention concerne un procédé de production de feuillets de graphène isolables et dispersibles, lesdits feuillets de graphène pouvant être spécialement conçus pour être solubles dans des solutions aqueuses, non aqueuses ou semi-aqueuses. Les feuillets de graphène hydrosolubles peuvent être utilisés pour la fabrication d'un composite nanoparticules métalliques-graphène présentant une aire de surface plus de 20 fois supérieure à celle des feuillets de graphène agrégés. Les feuillets de graphène solubles dans les solvants organiques peuvent être utilisés pour la fabrication de composites graphène-polymère.
