SUBSTRATE COMPRISING GRAPHENE AND PROCESS FOR PREPARING THE SAME

摘要

PURPOSE: A graphene material, and a producing method thereof are provided to easily produce graphene with the large area on a substrate, and to directly form the graphene without an intermediate layer. CONSTITUTION: A graphene material comprises graphene(40) combined with one side of a substrate(10) without wrinkles on more than 90% of the area of the substrate. The graphene has the peak rate of the D band/G band less than 0.5, when measuring with the Raman spectrum. The graphene material additionally includes a graphite catalyst layer(20) on the graphene.
