▎ 摘  要

NOVELTY - A reduced graphene oxide-based flexible transparent conductive thin film is obtained by plasma-treating a polyethylene terephthalate substrate to provide hydrophilic groups, bar-coating with a hydrophilic-phase-dispersed graphene oxide film, immersing in a solution of hydrogen iodide at 100 degrees C or less for reduction, washing formed reduced graphene oxide conductive thin film with ethanol, removing residual hydrogen iodide, and improving transmittance of obtain film. USE - Preparation of reduced graphene oxide-based flexible transparent conductive thin film useful as flexible transparent electrode in organic electroluminescent displays and organic solar cells. ADVANTAGE - The method enables simple and environmentally-friendly preparation of large-area (18x 20 cm2) reduced graphene oxide-based flexible transparent conductive thin films having high electroconductivity, transmittance, and mechanical performance, with high raw-material utilization rate. The obtained film overcomes the shortcoming of qualitative fragility of existing indium-tin oxide.
