Title (EN) PROCESS FOR OBTAINING STABLE DISPERSIONS OF AGGREGATES OF GRAPHENIC NANOFILAMENTS IN WATER AND PRODUCT OBTAINED THEREFROM
(FR) PROCÉDÉ D'OBTENTION DE DISPERSIONS STABLES D'AGGRÉGATS DE NANOFILAMENTS GRAPHÉNIQUES DANS DE L'EAU ET PRODUIT OBTENU À PARTIR DE CES DERNIERS
Abstract:
(EN) Process for obtaining stable dispersions of aggregates of graphenic nanofilaments in water and the product obtained by it from a mixture of aggregates of graphenic nanofilaments and water, wherein the graphenic nanofilaments have a special configuration in the form of a continuous spiral ribbon. Said mixture is subjected to a process divided into two main stages, a stage consisting of stirring the mixture in order to wet uniformly the aggregates of graphenic nanofilaments, and a stage consisting in a partial deaggregation and stretching of the aggregates of graphenic nanofilaments, resulting in a stable dispersion of modified aggregates of graphenic nanofilaments wherein their outer surface in contact with water is increased in order to enhance the interaction with the water of said modified aggregates, such that it is possible to determine a separation distance between the same that prevents their reaggregation.
(FR) L'invention concerne un procédé d'obtention de dispersions stables d'agrégats de nanofilaments graphéniques dans de l'eau et le produit obtenu à partir de ces derniers à partir d'un mélange d’agrégats de nanofilaments graphéniques et d'eau, les nanofilaments graphéniques ayant une configuration spéciale sous forme de ruban spiralé continu. Ledit mélange est soumis à un procédé divisé en deux stades principaux, un stade consistant à agiter le mélange afin de mouiller uniformément les agrégats de nanofilaments graphéniques, et un stade consistant en une désagréagation partielle et un étirage des agrégats de nanofilaments graphéniques, résultant en une dispersion stable d'agrégats modifiés de nanofilaments graphéniques, leur surface externe en contact avec l'eau étant accrue afin d'améliorer l'interaction avec l'eau desdits agrégats modifiés, de sorte qu'il est possible de déterminer une distance de séparation entre eux empêchant leur réagrégation.
