▎ 摘  要

NOVELTY - A graphene oxide synthesizing method involves oxidizing ground graphite using sulfuric acid and oxidizer in a medium of supercritical fluid, obtaining a mixture of sulfuric acid and dry ice in an amount sufficient to solidify a mixture of oxidizer and dry ice, with charging of the obtained mixtures into a high pressure autoclave, and mixing the reagents, where the mixture contains ground graphite. USE - Method for synthesizing graphene oxide that is utilized in electronics, medicine, pharmacology and construction industries. ADVANTAGE - The method enables synthesizing graphene oxide with high quality and high oxidation degree, and reduced consumption of sulfuric acid, in simple, safe and cost effective manner.
