Title (EN) PURIFICATION PROCESS FOR GRAPHENE NANORIBBONS
(FR) PROCÉDÉ DE PURIFICATION DE NANORUBANS DE GRAPHÈNE
Abstract: front page image
(EN)The present invention relates to a process for purifying graphene nanoribbons, which comprises: - bringing into contact a composition comprising graphene nanoribbons GNR1 and one or more contaminants with a liquid medium comprising a dispersant, and dispersing the graphene nanoribbons GNR1 in the liquid medium so as to obtain a liquid dispersion of the graphene nanoribbons GNR1, - subjecting the liquid dispersion of the graphene nanoribbons GNR1 to a separation treatment so as to at least partly remove the one or more contaminants, thereby obtaining a liquid dispersion of purified graphene nanoribbons GNR1.
(FR)Cette invention concerne un procédé de purification de nanorubans de graphène, comprenant : - la mise en contact d'une composition comprenant des nanorubans de graphène GNR1 et un ou plusieurs contaminants avec un milieu liquide comprenant un dispersant, et la dispersion des nanorubans de graphène GNR1 dans le milieu liquide de façon à obtenir une dispersion liquide de nanorubans de graphène GNR1, - la soumission de la dispersion liquide de nanorubans de graphène GNR1 à un traitement de séparation de façon à éliminer au moins partiellement le ou les contaminants, pour obtenir ainsi une dispersion liquide de nanorubans de graphène GNR1 purifiés.
