Title:

THREE-DIMENSIONAL GRAPHENE STRUCTURE SYNTHESIZING METHOD USING SPRAYING

Document Type and Number:

WIPO Patent Application WO/2017/188527

Kind Code:

A1

Abstract:

The present invention relates to a three-dimensional graphene structure synthesizing method using spraying and, more specifically, to a method which uses a spray to directly spray a reduced graphene oxide (RGO) solution in the form of liquid droplets onto a heated target surface so as to superheat and evaporate the solution, while establishing optimal related process conditions, so that the method can efficiently manufacture a self-assembled foam-like three-dimensional graphene structure having fine pores in a simple manner without an additional process. A three-dimensional graphene structure synthesized according to the present invention has graphene, which has excellent electrical conductivity and excellent thermal conductivity and is three-dimensionally formed, and thus has a maximized specific surface area. Therefore, the three-dimensional graphene structure can be applied to various fields, such as an electrode of a supercapacitor, an energy storage material, a heat transfer material related to nuclear power generation, and a desalting process.
