NOVELTY - The reduction method of graphene oxide involves preparing aqueous solution of graphene oxide in certain concentration, adding caffeic acid tablet, reflux-reacting at 80-100 degrees C for specific time, suction filtering, washing, and drying to obtain graphene. USE - Reduction of graphene oxide. ADVANTAGE - The method enables simple, economical and environmentally-friendly reduction of graphene oxide to produce graphene with excellent dispersibility and stability using drug caffeic acid tablet as reduction agent and without adding stabilizer and dispersant.
