▎ 摘　　要

NOVELTY - A graphite oxide material comprises acid solution and graphite oxide with solid content of 40-85 wt.%. USE - Graphite oxide material for preparing graphene oxide, reduced graphene oxide and graphene and graphene oxide dispersion (all claimed) used in energy, communication, building applications. ADVANTAGE - The graphite oxide material effectively solves the problem in the transportation of liquid graphene oxide and solid graphene oxide, and realizes easy transportation and saves storage space, and does not cause fire or explosion under collision during storage or transportation. The preparation method is simple, efficient and short, and does not require device and complicated purification and water removal steps, repeated drying and wetting processes, and produces product with high solid content, and is suitable for large-scale production. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of the graphite oxide material; and (2) graphene oxide dispersion, which comprises the graphite oxide material and water.
