ORNL demonstrates first large-scale graphene fabrication

(May 15, 2015)  One of the barriers to using graphene at a commercial scale could be overcome using a method demonstrated by researchers at the Department of Energy’s Oak Ridge National Laboratory.

Graphene, a material stronger and stiffer than carbon fiber, has enormous commercial potential but has been impractical to employ on a large scale, with researchers limited to using small flakes of the material.

Now, using chemical vapor deposition, a team led by ORNL’s Ivan Vlassiouk has fabricated polymer composites containing 2-inch-by-2-inch sheets of the one-atom thick hexagonally arranged carbon atoms.
