Superb Electrically Conductive Graphene Fibers via Doping Strategy.

Fibers with high electrical conductivity play an increasingly important role in many aspects of modern society. We use electrically conductive fi bers to generate, collect, and transmit signals and power with expected high effi ciency and less energy cost that defi nitely need high enough electrical conductivity. Beyond traditional metallic wires, carbon-based fi bers have attracted unprecedented attention due to their many fancy merits, such as lightness, environmental stability, and high electrical conductivity. The trend of seeking synthetic metal in carbonaceous fi bers has evolved from traditional carbon fi bers (CF), [ 1,2 ] carbon nanotube (CNT) fi bers [ 3–5 ] to the new graphene fi bers (GFs). [ 6 ] GFs can be fabricated by assembling individual graphene building blocks into uniaxial alignment, usually by high throughput wet-spinning from graphene liquid crystals in a continuous manner. [ 7 ] As a representative of graphene macroscopic material, GFs are hoped to inherit the exceptional properties of single graphene sheet, such as the record thermal and electrical conductivities, high carrier mobility, and outstanding mechanical fl exibility and strength. [ 8 ] Since its fi rst creation in 2011, GFs have demonstrated high potential in their overall performances and many attractive applications in multifunctional textiles, including electrical conductors, [ 9,10 ] fi ber-shaped solar cells, [ 11–13 ] fl exible supercapacitors, [ 14–16 ] smart sensors and actuators, [ 17–20 ] to name but a few.
