▎ 摘　　要

NOVELTY - Producing reduced graphene oxide comprises preparing first substrate; preparing seedlac solution by mixing seedlac with at least one solvent of alcohol, aliphatic hydrocarbon, alicyclic hydrocarbon, aromatic solvent, halogenated hydrocarbon, aldehyde, ketone, ether, ester, nitrile and sulfoxide solvents; providing the seedlac solution on the first substrate; and heat-treating the first substrate provided with the seedlac solution under a pressure of 13 mbar or less to obtain reduced graphene oxide formed on the first substrate. USE - The method is useful for producing reduced graphene oxide. ADVANTAGE - The method produces high-quality product, minimizes the interference of impurities and utilizes low cost raw materials. The reduced graphene oxide produced has high carbon content and high crystallinity, high thermal and electrical conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for reduced graphene oxide prepared by above method.
