Graphene Could Add Flex to Touchscreens

Oct-28-17 A touchscreen reinforced with graphene and silver nanowires could offer a flexible and more affordable alternative to current options.

Most touchscreens are made using indium tin oxide, a rare and expensive material. To reduce the use of such metals, the team from Sussex university added silver nanowires to the graphene film by floating the film on water, picking it up and then pressing it on a layer of silver nanowires. Adding graphene to the silver nanowire array increases the material’s conductivity while also reducing silver use.

According to lead researcher Matthew Large, "What we've also seen is that when we bend the hybrid films repeatedly the electrical properties don't change, whereas you see a drift in the films without graphene that people have developed previously. This paves the way towards one day developing completely flexible devices."
