Glasgow University Scientists Make 'Breakthrough' in Graphene Production

Herald Scotland reported that scientists at Glasgow University have made a “breakthrough discovery” that allows graphene to be produced 100 times more cheaply than ever before.
The scientists have found a way to make large sheets of the so-called “wonder material” using “the same type of cheap copper used to manufacture lithium-ion batteries.”
As quoted in the market news:

Graphene is usually produced by a process known as chemical vapour deposition, or CVD, which turns gaseous reactants into a film of graphene on a special surface known as a substrate.
The research team at Glasgow used a similar process, but used commercially-available copper foils, often used as the negative electrodes in lithium-ion batteries, as a surface on which to create high-quality graphene.
Researchers also observed the surface of the copper used provided an excellent bed for the graphene to form upon.
The university’s technique of producing graphene not only reduced the cost but offered a stark improvement in the electrical and optical performance of the material, compared to the older, more expensive, process.
