Abstract

We introduce a novel procedure for producing flexible transparent conductive graphene films. The synthetic procedure includes a solution-processed chemical reduction and an anodized aluminum oxide (AAO) membrane filter-assisted thermal reduction. The final flexible transparent graphene films produced by this method exhibited a sheet resistance of less than 850 Ω sq−1 with 80% transmittance under visible-light irradiation (wavelengths: 540–840 nm). This sheet resistance value is much lower than that of graphene films obtained from solution-processed approaches (usually, in 103–104 Ω sq−1).
