Title
(EN) METHODS FOR DISPERSING CARBON NANOTUBES AND COMPOSITIONS USED FOR THE METHODS
(FR) PROCÉDÉS POUR DISPERSER DES NANOTUBES DE CARBONE ET COMPOSITIONS UTILISÉES POUR LES PROCÉDÉS
Abstract
(EN) The present invention refers to a method of dispersing carbon nanotubes in a thermosetting resin. The method comprises: (a) contacting the carbon nanotubes with a dispersant in a solvent to form a dispersion mixture, wherein the dispersant is a graft polymer comprising a polymeric backbone and a side chain grafted to the polymeric backbone; and (b) adding the thermosetting resin to the dispersion solution to form a resin blend. The present invention also refers to a composition used for the method.
(FR) La présente invention porte sur un procédé de dispersion de nanotubes de carbone dans une résine thermodurcissable. Le procédé met en œuvre : (a) la mise en contact des nanotubes de carbone avec un agent dispersant dans un solvant afin de former un mélange de dispersion, l'agent dispersant étant un polymère greffé comprenant une chaîne principale polymère et une chaîne latérale greffée sur la chaîne principale polymère; et (b) l'ajout de la résine thermodurcissable à la solution de dispersion afin de former un mélange de résine. La présente invention porte également sur une composition utilisée pour le procédé.
