Abstract: Provided is a method for continuously preparing graphene oxide nanoplatelets by electrochemical treatment, comprising using a continuous graphite product, successively processing two step treatments, i.e. an electrochemical intercalation and an electrolytic oxidation stripping. The electrochemical intercalation is carried out in a concentrated acid, using a graphite material as an anode and energizing under a soaking condition such that acid radical ions enter into graphite interlamination under the drive of an electric field, to form an intercalated graphite continuous material with first-order or low-order intercalation. The electrolytic stripping is using the intercalated continuous graphite material as an anode, energizing in an aqueous electrolyte solution, and performing oxidation stripping.
