NOVELTY - Preparation method of nickel-plated graphene involves (a) mixing graphene and deionized water and then stirring to obtain graphene solution, adding DL-malic acid and nickel salt to the graphene solution and ultrasonically processing to obtain mixed solution (I), (b) adjusting pH of the mixed solution (I) to 10 using alkaline solution, adding sodium borohydride and carrying out reduction reaction to obtain mixed solution (II), and (c) adding nickel salt and sodium borohydride to mixed solution (II), ultrasonically processing, centrifugally washing and drying to obtain nickel-plated graphene. USE - Method is useful for preparing nickel-plated graphene, which is useful for preparing graphene composite material. ADVANTAGE - The method ensures rapid, economical and environmentally-friendly preparation of nickel-plated graphene without performing activation and sensitization process, and is suitable for large-scale production.
