▎ 摘　　要

NOVELTY - Preparing a graphene foam comprises taking nickel foam and then processing using plasma technology, soaking the processed nickel foam in a solution of graphene oxide, uniformly mixing to obtain a nickel foam solution, coating the solution using a corrosive agent, repeatedly washing the coated solution using anhydrous ethyl alcohol and water, and drying. USE - The method is useful for preparing a graphene foam (claimed). ADVANTAGE - The method simply and easily prepares the graphene foam with high yield and porosity, and reduced cost in a convenient manner.
