Graphene Continuously Produced at 1 Inch per Minute
• arcleinThe new process is an adaptation of a chemical vapor deposition method already used at MIT and elsewhere to make graphene using a small vacuum chamber into which a vapor containing carbon reacts on a horizontal substrate, such as a copper foil. The new system uses a similar vapor chemistry, but the chamber is in the form of two concentric tubes, one inside the other, and the substrate is a thin ribbon of copper that slides smoothly over the inner tube.
