Title (EN) GRAPHENE BASED FIBERS AND PRODUCTION METHOD THEREOF
(FR) FIBRES À BASE DE GRAPHÈNE ET LEUR PROCÉDÉ DE FABRICATION
Abstract:
(EN) The present invention proposes a method for preparation of graphene-based fibers, comprising releasing of an aqueous graphene oxide (GO) suspension with a GO concentration of at least 20 g/L, through a nozzle, into an ionic solution, thus formation a longitudinal fiber; and then taking the fiber out of the ionic solution and then contacting the fiber with a solvent having a higher polarity than that of water. The present invention further proposes a stable aqueous graphene oxide suspension allowing formation of fibers therefrom.
(FR) La présente invention concerne un procédé de préparation de fibres à base de graphène qui comprend la libération d’une suspension aqueuse d'oxyde de graphène (GO) ayant une concentration en GO d'au moins 20 g/L, par une buse, dans une solution ionique, formant ainsi une fibre longitudinale ; puis l'enlèvement de la fibre de la solution ionique, et ensuite la mise en contact de la fibre avec un solvant ayant une polarité supérieure à celle de l'eau. La présente invention concerne en outre une suspension aqueuse stable d'oxyde de graphène permettant la formation de fibres à partir de ladite suspension.
