摘要：
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 Omega 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 10(3)-10(4) Omega sq(-1)).
