A new technique to manufacture graphene could lead to a new era for electronic displays, according to a report published by a team of researchers from the University of Glasgow. Graphene is a thin layer of carbon that is more than 200 times stronger than steel, conducts heat and electricity, and is nearly transparent.
By using the ultrasmooth copper foils found in lithium-ion batteries, researchers were able to drive down production costs from $115 per square meter to $1. Devices using the graphene sheets performed better in tests.
“Large-scale and low-cost synthesis of high-quality graphene films and the compatibility of our method to the roll-to-roll fabrication would open an avenue through the realization of graphene-based flexible optoelectronic systems such as cellphones with roll-up displays, e-paper, radio-frequency identification (RFID) tags, as well as medical patches that can be attached to the skin,” the researchers wrote in their report.
