Researchers develop a cheaper, scalable method to make graphene

Researchers from the University of Pennsylvania developed a new cost-effective method to make Graphene. The new method is said to be scalable for commercialization as it uses readily available materials and manufacturing processes at ambient pressures. The researchers report that the Graphene sheet was one atom thick in 95% of its area.
The team used chemical vapor deposition (CVD) but used smooth copper foil instead of costly custom copper sheets. The team 'electropolished' the foil and this was smooth enough to produce single-layer graphene (in 95% of the area).
