Production of Graphene-Containing Suspensions for Liquid-Phase Shear Exfoliation of Graphite

Abstract

A method and device for obtaining graphene-containing suspensions by liquid-phase shear exfoliation of graphite in a continuous mode have been developed. The comparison of the intensities of the process of exfoliation of graphite in the periodic and continuous modes was carried out and it was found that the intensity of the exfoliation process in the continuous mode is higher than in the periodic one. The limiting concentration of graphene structures in a suspension is reached 1.5 times faster when using an apparatus operating in a continuous mode than in a periodic mode, and its numerical value is greater (by at least 25 %).
