Despite noteworthy progress in the fabrication of large-area graphene sheetlike nanomaterials, vapor-based processing still requires sophisticated equipment and a multistage handling material. An alternative approach to manufacturing functional graphene-based films includes employment oxide (GO) micrometer-scale sheets as precursors. However, search for scalable technique production high-quality GO nanoscale with high uniformity electrical conductivity is continuing. Here we show that conventional dip-coating can offer quality mono- bilayered made sheets. The method based on our recent discovery encapsulating individual nanometer thick molecular brush copolymer layer allows nearly perfect formation layers via dip coating from water. By thermal reduction bilayers (cemented by carbon-forming polymer linker) are converted into highly conductive transparent reduced up 104 S/cm optical transparency level 90%. value highest reported thermally close indium tin currently use electronic devices, thus making these intriguing candidates replacement ITO films.
