Transparent and flexible graphene conductive films had been investigated via Langmuir-Blodgett assembling technique. Firstly, Hummers method is improved to prepare graphene oxide. Then, the graphene oxide sheets are formatted with the edge connected and sheet stacked structure by the Langmuir-Blodgett assembling technique. Finally, the reduced graphene oxide films are attained by HI vapor reduction at a low temperature. Furthermore, the relationship between the transmittance of assembling layers and their corresponding conductive is studied, and the graphene sheet with the transmittance of 82.69% is obtained at 550 nm wavelength with the sheet resistance of 471 Ω/□ of the transparent conductive thin film in edge-connecting structure.
