Stretchable, Conductive Graphene Yarn

Jun-25-14 Researchers have developed a flexible, stretchy graphene yarn that could potentially equal copper's level of conductivity.

The yarn, created by teams from Pennsylvania State University and Shinshu University, was made by mixing flakes of graphene with water to form a slurry, and then spreading that slurry on a plate to dry. The resulting thin, transparent film was then removed from the plate and cut into strips that were wound together to create a conductive 'yarn.'

The yarn is reported to be significantly stronger than other carbon fibers, perhaps due to the air pockets that keep it from becoming brittle, and its conductivity could be improved with the removal of oxygen from the fibers or the addition of silver nanorods to the film.
