▎ 摘　　要

NOVELTY - Preparing oxidized graphene nano-roll involves utilizing silver as a catalyst, breaking carbon-carbon bond of the graphene oxide sheet in the atmosphere of amine to obtain nano-graphene oxide nano-fragments, and self-rolling the nano-graphene oxide nano-fragments under the action of inter-hydrogen bonds to obtain oxidized graphene coil. USE - Method for preparing oxidized graphene nano-roll that is used for preparing antibacterial agent (claimed), and in medical and sanitary materials, conductive materials, water treatment, air purification and other fields. ADVANTAGE - The method prepares oxidized graphene nano-roll in simple, short, less pollution and less impurity manner. The obtained nano graphene oxide nano-roll has uniform diameter and length distribution, firm structure, and excellent antibacterial, electrical conductivity, adsorption, catalysis and other properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a nano graphene oxide coil prepared by the method.
