Abstract

A process for producing a carbon nanosheet, capable of industrial mass production of a carbon nanosheet. The process comprises the chemical oxidation step of immersing a raw material of carbon nanosheet in a strong oxidant and inducing an electrochemical oxidation reaction; the water washing/ultrasonic treatment step of performing washing while applying ultrasonic waves; the solid-liquid separation step of performing solid-liquid separation; the drying/heat treatment step of drying and heating carbon solid; the water washing/ultrasonic treatment step of washing the heated carbon solid with water or an alkali while applying ultrasonic waves; the solid-liquid separation step of performing solid-liquid separation for the carbon solid having undergone washing and ultrasonic treatment; the flotation screening step of sequentially adding water and a foaming agent to the carbon solid resulting from the solid-liquid separation and screening a carbon nanosheet; the water washing/solid-liquid separation step of washing the screened carbon nanosheet with water and thereafter performing solid-liquid separation of the liquid carbon nanosheet mixture; and the drying step.
