▎ 摘　　要

NOVELTY - The chemical vapor deposition (CVD) method for growing large area graphene, involves using untreated rolled metal as the growth substrate of CVD graphene, using the grease remaining on the metal surface, using grown graphene as carbon source, using untreated rolled metal as the substrate of CVD graphene growth, using the surface of residual grease as carbon source of graphene growth, directly placing the materials into a CVD system to grow, forming the large area of graphene on the surface. USE - Chemical vapor deposition (CVD) method for growing large area graphene at low cost. ADVANTAGE - The method eliminates the need for external carbon source, reduces the preparation cost large area graphene.
