▎ 摘　　要

NOVELTY - Producing a reduced graphene oxide scroll comprises (a) preparing dispersion solution by dispersing reduced graphene oxide in an organic solvent, (b) drying the organic solvent of the dispersion solution to form a laminate in which multiple reduced graphene oxides are stacked, (c) preparing a first mixture by mixing the laminate with water, and (d) preparing a second mixture including a reduced graphene oxide scroll by irradiating the first mixture with ultrasonic waves. USE - The reduced graphene oxide scroll is useful in energy storage field i.e. battery or a supercapacitor. ADVANTAGE - The method is simple and easily prepares a carbon nanoscroll structure in water without using ions such as potassium hydroxide. The reduced graphene oxide scroll has high electron mobility, high thermal conductivity, and excellent anisotropic mechanical stiffness.
