▎ 摘　　要

NOVELTY - The method involves mixing perchloric acid and nitric acid with chromate solution at volume ratio of 4:3 to obtain reaction mixture. Graphite is added with the reaction mixture. The graphite and the reaction mixture are stirred for 24 hours at temperature of 50 degrees Celsius. Graphene oxide is separated from the reaction mixture by filtration membrane. The graphene oxide separated reaction mixture is dried for 24 hours at temperature of 100 degrees Celsius. USE - Method for obtaining two-layer graphene oxide.
