Road to Graphene Fiber: Continuous, ultrastrong graphene fibers are wetspun from giant graphene oxide liquid crystals, as reported by Chao Gao and co-workers on page 188. The giant size and regular alignment of graphene sheets give the fibers high mechanical strength (up to 0.5 GPa) and good electrical conductivity. Such graphene fibers promise wide applications in functional textiles, flexible and wearable sensors, and supercapacitor devices.
