文摘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.
