A Hybrid Reduction Procedure for Preparing Flexible Transparent Graphene Films with Improved Electrical Properties

doi:10.7517/j.issn.1674-0475.2012.04.289

Abstract

Abstract: A novel procedure for producing flexible transparent conductive Graphene films was reported. The synthetic procedure includes a solution-processed chemical reduction and an anodized aluminum oxide (AAO) membrane filter-assisted for thermal reduction. Final flexible transparent graphene films produced by this method exhibited the sheet resistance less than 850 Ω/square with 80% transmittance under visible-light irradiation (wavelengths: 540-840 nm). This sheet resistance value is close to that of the graphene films obtained from CVD method (280-770 Ω/square), and is much lower than that of the graphene films obtained from solution process (usually, in 10³-10⁴Ω/square).

Key words: flexible conductive graphene films, transferring methods, thermal reduction, AAO membrane filter, graphene
