Inspired by the traditional Chinese pancake-making method, the efficient electromagnetic interferences (EMI) shielding composite carbon films are conveniently obtained by assembling graphene oxide (GO) sheets, carbon nanotubes (CNTs), and Co/C nanocomposites into a laminated nacre-like structure. The developed composite carbon films are characterized by a shielding effectiveness (SE) up to approximate to 51 dB in X band with a small thickness of approximate to 34.3 mu m. Moreover, the composite carbon film shows favorable flexibility and the SE values almost keep a constant after repeatedly bending test. These results demonstrate a promising approach to simply fabricate a flexible and highly efficient EMI shielding material.
