▎ 摘　　要

NOVELTY - Preparing graphene in liquid phase comprises (a) mixing pre-determined percentage of water and alcohol directly to obtain the solution, (b) dispersing the graphite powder into the solution to obtain the graphite dispersing liquid, (c) treating the liquid with ultrasonic cavitation or effluxing cavitation, (d) standing the treated solution and then taking the upper layer solution, (e) performing high-speed centrifuging separation on the upper layer solution, and (f) collecting out the centrifugate to obtain the stable graphene dispersing liquid. USE - The method is useful for preparing graphene in liquid phase. ADVANTAGE - The method is capable of easily and economically preparing graphene in liquid phase with low boiling point and excellent reproducibility in an environmentally friendly manner. DESCRIPTION OF DRAWING(S) - The figure shows a flow chart of a method for preparing graphene in liquid phase (Drawing includes non-English language text).
