▎ 摘　　要

NOVELTY - Preparation of reduced graphene oxide involves preparing aqueous solution of graphite oxide and glucose, performing hydrothermal reaction process, obtaining reduced graphene oxide gel, and dispersing the obtained reduced graphene oxide gel in aqueous acetic acid solution and removing water from the resultant product to obtain reduced graphene oxide powder. USE - Preparation of reduced graphene oxide used for preparing suspension (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of reduced graphene oxide suspension, which involves adding reduced graphene oxide powder to a mixed solvent of dimethylformamide and deionized water, and performing ultrasonic treatment to disperse the reduced graphene oxide powder.
