Title (EN) PROCEDURE FOR THE MANUFACTURING OF EMULSIONS OF GRAPHENE OXIDE AS WELL AS REDUCED GRAPHENE OXIDE–ENCAPSULATED NANOPARTICLES
(FR) PROCÉDÉ DE FABRICATION D'ÉMULSIONS D'OXYDE DE GRAPHÈNE ET NANOPARTICULES ENCAPSULÉES DANS DE L'OXYDE DE GRAPHÈNE RÉDUIT
Abstract:
(EN) In order to provide for a procedure for the manufacturing of emulsions in order to provide for materials that may be useful especially in energy devices, it is suggested a procedure comprising the steps of - preparation of a first solution of at least one element and/or at least one compound selected from a group comprising sulfur, silicon, metals and/or metal oxides, in at least one non-aqueous solvent; - preparation of a second, aqueous solution of graphene oxide; - preparation of a combined solution by combining the first solution and the second, aqueous solution; - adding of at least one surfactant to the first and/or second and/or combined solution; - emulsifying the combined solution.
(FR) Cette invention concerne un procédé de fabrication d'émulsions afin de fournir des matériaux qui peuvent être utiles notamment dans des dispositifs énergétiques. Un procédé selon l'invention comprend les étapes consistant à : -préparer une première solution d'au moins un élément et/ou d'au moins un composé choisi dans un groupe comprenant le soufre, le silicium, des métaux et/ou des oxydes métalliques, dans au moins un solvant non aqueux ; -préparer une seconde solution d'oxyde de graphène aqueuse ; -préparer une solution combinée par combinaison de la première solution et de la seconde solution aqueuse ; -ajouter au moins un tensioactif à la première et/ou à la seconde solution et/ou à la solution combinée ; -émulsifier la solution combinée.
