Graphene, a single layer of carbon atoms bonded in a hexagonal lattice, is the thinnest,
strongest, and stiffest known material and an excellent conductor of heat and electricity.
However, these superior properties have yet to be realized for graphene-derived
macroscopic structures such as graphene fibers. We report the fabrication of graphene fibers
with high thermal and electrical conductivity and enhanced mechanical strength. The inner
fiber structure consists of large-sized graphene sheets forming a highly ordered …
