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. The method has the following advantages: a product does not contain a metal impurity, the oxidation degree of graphene is controllable, the process is continuable and automatable, and the method is safe and has low emissions, etc.

Claim (Index 7):
