The present invention relates to a kind of redox graphene laminated film and preparation method thereof, this method includes (1) improvement Hummer methods and prepares the hypoxemia graphite aqueous solution；(2) preparation of suboxides graphene oxide/amphipathic nature polyalcohol dispersion liquid；(3) fractional centrifugation；(4) in-situ polymerization；(5) film forming is filtered；(6) composite membrane is prepared；(7) reduce；Under the conditions of 70 80 DEG C, composite membrane is immersed in 10~15s in the HI aqueous solution, taken out, then cleans and dries；Obtain redox graphene laminated film.5 × 5cm of redox graphene laminated film prepared by the present invention is without any crack and fold, 0 180 ° of any bendings, and the light transmittance 85% 88% at λ=550nm, electrical conductivity reaches 91.6 98.2S/cm, and sheet resistance is 145.82 175.54 Ω sq ‑1 ；Raman spectrum shows that PEDOT groups and structure are completely the same before and after HI reduction. |
