Scientists produce graphene 100 times cheaper than ever before

However the cost of graphene in comparison to more traditional electronic materials has meant that its uptake in electronic manufacturing has been slow. Now researchers at the University of Glasgow have discovered a way to create large sheets of graphene using the same type of cheap copper used to manufacture lithium-ion batteries.

As a two-dimensional crystal of carbon atoms, graphene is a basic building block of many carbon derivatives such as zero dimensional fullerene, one dimensional carbon nanotubes, and three dimensional graphite. These carbon based nanomaterials have all been used in electronics to create everything from solar cells to light bulbs and ultrasensitive gas sensors. To produce high-quality material scaled-up for electronics on large areas, though, graphene has proved more expensive than standard electronic substrates such as silicon.
