▎ 摘　　要

NOVELTY - Reduction of graphene oxide involves annealing graphene oxide deposited on a substrate in presence of a graphitic material under vacuum to form reduced graphene oxide. USE - Reduction of graphene oxide used in electronic device (claimed). Uses include but are not limited to field effect transistor, transparent conducting electrode, sensor and memory device. ADVANTAGE - The method enables easy, economical and environmentally-friendly graphene oxide reduction without using harmful chemicals and equipment, and provides reduced graphene oxide having high electroconductivity and field effect mobility, and low electrical resistance.
