▎ 摘  要

NOVELTY - Preparing electromagnetic shielding graphene comprises (i) cleaning graphene surface, (ii) carrying out high temperature oxidation treatment of graphene obtained in step (i), and (iii) immersing graphene obtained in step (ii) in nickel nitrate solution, drying, repeating operations, and performing hydrogen reduction to obtain final product, where mass ratio between nickel and graphene is 13-19:85-92. USE - The method is useful for preparing electromagnetic shielding graphene (claimed). ADVANTAGE - The method: produces the product having enhanced bonding strength, improved shielding property and corrosion resistance; and has simple process.
