Abstract
A method for preparing a graphene-coated powder material, comprising: A) dispersing a graphene powder and/or graphene oxide powder, a powder material to be coated with graphene, and a polymeric co-coating agent in a first organic solvent to form a first organic solvent dispersion; B) mixing the first organic solvent dispersion with a second organic solvent and separating a precipitate after sedimentation; and C) annealing the precipitate in an inert atmosphere to obtain the graphene-coated powder material; wherein the polymeric co-coating agent is soluble in the first organic solvent but insoluble in the second organic solvent. The present invention also relates to a graphene-coated powder material prepared by the method.
