Recently, researchers at the University of Glasgow in Scotland have discovered how to produce large sheets of high-quality graphene in a way that is 100 times less expensive than previous methods.
“The University of Glasgow team decided to see if they could make graphene with copper foils, which are already being cheaply made in bulk to create common household lithium-ion batteries. Without any processing, they found that these copper foils were smooth enough to make high-quality single-atom sheets of graphene,” ScienceAlert.com reported.
“The graphene sheets displayed optical electrical properties that made them better suited for use in transistors than sheets that had been produced with an expensive substrate,” ScienceAlert.com added.
This discovery could make it possible for scientists to use graphene in technologies such as high-tech filters and materials, as well as medical devices.
