Embodiment Construction
[0034] Hereinafter, a method for preparing graphene with low impurity content according to the present invention will be described in detail with reference to the accompanying drawings and exemplary embodiments.
[0035] Specifically, on the one hand, in the process of producing graphene oxide, especially in the process of producing graphene oxide by oxidation intercalation, impurity ions will combine with graphene oxide, which leads to low purity of graphene oxide. Existing graphene oxide purification methods have problems such as low efficiency and insufficient thoroughness. However, in the purification process of graphene oxide, the present invention simultaneously applies the method of complexing agent and dilute hydrochloric acid washing, and cooperates with ultrasonic action, so as to more effectively separate graphene oxide and impurity ions, and simultaneously isolate impurity ions Under the action of the complexing agent, it will not be combined with graphene oxide, t...
