▎ 摘  要

NOVELTY - A graphene preparation method includes the following steps: (a) oxidizing a graphite material to form a graphite oxide; (b) dispersing the graphite oxide in water for obtaining an oxidized graphite suspension; (c) adding a dispersant into the graphite suspension; and (d) adding an acidic reductant into the oxidized graphite suspension for carrying out reduction with the oxidized graphite so as to form a graphene, and then carrying out a bonding reaction between the graphene and the dispersant and finally obtaining a graphene suspension containing a surface-modified graphene. The present invention uses acidic reductant to prepare graphene, such that the graphene obtained by this method can homogeneously be dispersed in water, acidic solution, alkaline solution or organic solvent to obtain a homogeneously graphene dispersion.
