PROCESS FOR GRAPHENE BASED TRANSPARENT ELECTRODE WITH NO RESISTANCE CHANGE BY CURVATURE

摘要

PURPOSE: A method for manufacturing a graphene-based transparent electrode without resistance variation due to a curvature is provided to utilize a largely synthesized graphene, thereby obtaining a transparent conductive thin film having an electric resistance which is almost not varied when the film is bent and a high optical transmittance. CONSTITUTION: A method for manufacturing a graphene-based transparent electrode includes: a step of injecting a vapor carbon source on a substrate at a temperature of 1000°C and at a pressure of 2.2Torr; a step of reacting the substrate with carbon from the source; a step of quickly cooling the carbon, which is reacted with the substrate, up to ambient temperature, and growing a graphene sheet (110) on the surface of the substrate; a step of etching the substrate having the sheet, and separating the sheet from the substrate; a step of moving the sheet in deionized water, and washing the sheet; and a step of transferring the sheet onto a polyethylene terephthalate (PET) transparent substrate (120).
