▎ 摘　　要

NOVELTY - Electrochemical method of graphene oxide deposition involves preparing graphite solution by adding graphite to dispersion, oxidizing obtained graphite solution, obtaining graphene oxide solution, carrying out electrochemical deposition of graphene oxide on substrate by applying potential to graphene oxide solution as working electrode, reference electrode and counter electrode, and heat-treating the substrate on which the graphene oxide is deposited. USE - Electrochemical method of graphene oxide deposition used for forming graphene oxide-deposited substrate for electrical device e.g. illuminator, display device or solar cell (all claimed). ADVANTAGE - The method efficiently and economically provides graphene oxide-deposited substrate having excellent electron transfer efficiency, in short period of time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene oxide-deposited substrate.
