▎ 摘  要

NOVELTY - Preparing graphene oxide film comprises dispersing the graphite oxide powder and the graphene oxide filter cake into the solvent to obtain the graphene oxide slurry, defoaming the graphene oxide slurry, coating, drying and peeling to obtain the graphene oxide film, where the graphene oxide filter cake is oxidized graphene slurry prepared by oxidationreduction method through filter pressing, the graphite oxide powder is prepared by graphene heat-conducting film generating the leftover material and defective product of graphene oxide and drying, crushing and crushing to obtain the graphene oxide powder. USE - The method is useful for preparing graphene oxide film. ADVANTAGE - The method improves utilization rate of the raw material, and reduces manufacturing cost.
