摘　　要：Bio-mimicking graphene films,deposited on textured nickel substrates,were synthesized by the following method:replicating the surface textures of the lotus leaf by polymer duplication,fabricating textured nickel substrates by electroplating on the polymer coated with a Au film,preparing bio-mimicking graphene oxide films on the nickel substrates by vacuum filtration,and electrochemical reduction.By controlling the vacuum filtration,this replica method can not only replicate the lotus leaf structure by a graphene film,but also can achieve a novel cell-like graphene film.Bio-mimicking graphene films, deposited on textured nickel substrates, were synthesized by the following method： replicating the surface textures of the lotus leaf by polymer duplication, fabricating textured nickel substrates by electroplating on the polymer coated with a Au film, preparing bio-mimicking graphene oxide films on the nickel substrates by vacuum filtration, and electro- chemical reduction.
