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 3):
The method of continuously preparing graphene oxide nanoplatelet according to  claim 1 , characterized in that, the process of preparing graphene oxide comprises the steps of: sequentially processing an electrochemical process in two different devices defining a first process and a second process, wherein in the first process, a process of electrochemical intercalation is carried out, wherein in the second process, a process of electrochemical electrolysis for oxidation and exfoliation is carried out; the graphite raw material is first driven by a feeding device and sequentially passes through the two different devices, then the graphene oxide nanoplatelet is formed in the second device; in the two processes which are carried out in the two different devices, the graphite raw material are used as anodes and inert electrode materials are used as cathodes respectively, then power is connected to carry out electrochemical reaction.
