Abstract
A method of manufacturing graphene, including forming a metal catalytic layer on a substrate (Step a), providing a cover member on the metal catalytic layer of Step a (Step b), and growing graphene on the metal catalytic layer of Step b by performing chemical vapor deposition (Step c), whereby the size of the micro-scale grain boundary on the surface of the metal catalyst can be reduced by simultaneously promoting the aggregation of metal catalytic molecules in a chemical vapor deposition device and preventing the evaporation of the metal catalyst due to the effect of the cover member, ultimately improving the quality of synthesized graphene, including the transparency thereof. Also, a graphene sheet can be grown under various concentrations of carbon source gas, and efficient mass production thereof is possible in a chemical vapor deposition device having a confined space.
