Abstract

Graphene fibers (GFs) with superb electrical conductivity are produced via a chemical doping strategy. The electrical conductivities reach up to 0.77 × 10⁷ -2.24 × 10⁷ S m^-1 , which are the highest values among all the reported GFs. The combination of lightness, superb conductivity, and easy scalability makes GFs a promising new carbonaceous fiber species with high performance and advanced functionality.

Keywords: chemical doping; graphene fibers; supermetallic conductivity.
