Methods of manufacturing graphene and conductor

Abstract

The present invention relates to a technique for manufacturing graphene and, more particularly, to a method for manufacturing graphene and a method for manufacturing a conductor using the graphene manufacturing method, which uses the exfoliating or transferring functions of various structures having the physical properties and adhesion peculiar to graphite to manufacture graphene on a large scale and also an electrical conductor or a thermal conductor from the graphene. One aspect of the method for manufacturing graphene and the method for manufacturing a conductor using the graphene manufacturing method is that the method for manufacturing graphene includes: (a) exfoliating or transferring a graphite material onto at least one structure to form graphene particles on the surface of any one of the at least one structure; (b) releasing the graphene particles from the structure; and (c) combining the released graphene particles to form graphene. Another aspect of the method for manufacturing graphene and the method for manufacturing a conductor using the graphene manufacturing method is that the method for manufacturing graphene includes: (a) consecutively exfoliating or transferring a graphite material onto a plurality of structures to form graphene particles on the surface of any one of the plural structures; (b) releasing the graphene particles from the structure; and (c) combining the released graphene particles to form graphene.

Description

Technical field [0001] The present invention relates to a technology for manufacturing graphene, and more specifically to a method for manufacturing graphene and a method for manufacturing an electrical conductor, which utilizes the physical properties of graphite and the peeling effect or transfer effect of various viscous structures to produce graphite in large quantities Ene, and make electrical conductors or thermal conductors from the manufactured graphene. Background technique [0002] Compared with metals such as copper and aluminum, graphene has excellent electrical conductivity, thermal conductivity, mechanical strength, and optical transparency. [0003] Graphene has a hexagonal honeycomb-like structure stacked in layers. The graphene is formed into a visible light and wide area to maintain desired characteristics. Graphene with these excellent characteristics is suitable as a transparent electrode material for solar cells, semiconductors, nuclear fusion reactors, batte...
