Abstract:
PURPOSE: A method for manufacturing a pure graphene sheet using a polyvinyl alcohol(PVA)-coagulating method and the graphene sheet are provided to eco-friendly implement a pure graphene sheet separating process using a PVA solution without an additional reducing agent such as sodium hydroborate and hydrazine. CONSTITUTION: Graphite is oxidized by being dispersed in sulfuric acid and being stirred using potassium permanganate in order to obtain graphite oxide which is composed of a plurality of graphene layers. The graphite oxide is undergone an ultrasound-wave treatment to be separated into a graphene oxide sheet. The graphene oxide sheet is reduced using a reducing agent and reacted with a PVA solution. A pure graphene sheet is separated.
