APPARATUS FOR PRODUCING GRAPHENE

Document Type and Number:

WIPO Patent Application WO/2023/068389

Kind Code:

A1

Abstract:

An apparatus for producing graphene is provided. The apparatus for producing graphene according to an embodiment of the present invention may comprise: a supply part which supplies graphite oxide powder or graphene oxide powder; a moving part which is coupled at one side thereof to the supply part, includes a moving part body within which a moving surface having a predetermined width and extending in one direction from one side thereof and a moving space above the moving surface are formed, and is supplied from one side of the moving space with the graphite oxide powder or graphene oxide powder supplied from the supply part and moves same to the other side of the moving space; a laser radiation part which radiates laser beams onto the moving path of the graphite oxide powder or graphene oxide powder to produce graphene powder from the graphite oxide powder or graphene oxide powder; and a collection part which is connected to the other side of the moving part, and separates the graphene powder from the graphite oxide powder or graphene oxide powder and collects the separated graphene powder.
