NOVELTY - A self-assembly preparation method of noble-metal-graphene double-layer composite conductive film, comprises mixing a noble metal precursor solution and graphene oxide dispersing solution with dispersing agent or mixing without adding dispersing agent according to a given proportion, transferring the mixed solution to different substrates, evaporating solvent and self-assembling, and treating with hydrazine stream. USE - The self-assembly preparation method is useful for noble-metal-graphene double-layer composite conductive film (claimed). ADVANTAGE - In the self-assembly preparation method, the thicknesses of the noble metal layer, the graphene layer of the double-layer composite conductive film, and the whole film can be regulated and controlled through concentration and volume of the noble metal ion solution and graphene oxide solution. Moreover, the conductivity of the silver layer and the graphene layer of the double-layer composite conductive film is controllable.
