Abstract: The present disclosure relates to a method of growing a graphene nanopowder having a size of 10 nm or less into a graphene sheet having a seed size or more by using a graphene nanopowder as a seed. Further, in the present disclosure, a graphite sheet in which 2 to 20 layers of the graphene sheet are laminated may be prepared. The carbon sheet (that is, graphene and graphite sheets) may be prepared by preparing a graphene nanopowder (randomly distributed) on a substrate, and then subjecting the substrate to CVD treatment using a gas including a hydrocarbon gas in a chemical deposition apparatus.
