New method yields cheaper CVD graphene

Researchers from Glasgow University have come up with a method to mass produce graphene in a process that is reportedly much cheaper to employ than the current one.

The team used CVD in their research, but instead of using the traditional surface, used copper foils as the surface wherein high-grade graphene is created. As these copper foils are much cheaper than the usual substrate, the cost of production decreased dramatically.

The copper's surface proved an excellent substrate for graphene production. Not only is it cost effective, but the researchers also found an improvement in the optical and electrical performance of the resulting graphene compared to traditionally-made graphene. In that way, the process has not changed, but by changing the ingredients it was made much cheaper - which could greatly contribute to the material's mass production and acceptance.
