New method to quickly transfer graphene sheets from metallic substrate without any damage

Researchers from Korea's KAIST institute in collaboration with researchers from Korea University and the KIMM institute developed a new method to transfer graphene from a metallic substrate to any other substrate without any damage to the graphene. The method is very fast and is not expensive.

Current transfer processes can introduce impurities or even damage pure graphene sheets when the are transferred after being synthesized using CVD. The new method, however, uses heat, an electric field and mechanical pressure to attach the graphene to a new substrate using a strong adhesive force. The metallic substrate is pulled away mechanically.
