Single-layer edge-oxidized graphene and preparation method thereof

Abstract

An edge-oxidized single-layer graphene and a preparation method thereof are provided. The preparation method includes: mixing a single-layer graphene, a binder, and a dispersant, and drying a resulting slurry to obtain an electrode plate; and subjecting the electrode plate to electrolytic oxidation in an electrolytic cell to obtain the edge-oxidized single-layer graphene; wherein the electrolytic oxidation is conducted under an ultra-low frequency alternating current having a frequency of 0.01 Hz to 0.02 Hz; and the electrolytic oxidation is conducted at a current density of 30 mA·cm−2 to 50 mA·cm−2 for 50 s to 100 s.
