Abstract

We fabricated reduced graphene oxide fiber through wet spinning and chemically reduction method. We observed the reduction of graphene oxide by using Raman spectroscopy and X-ray photoelectron spectroscopy. The mechanical and electrical properties of reduced graphene oxide fiber were also measured and both properties were improved by reduction of graphene oxide fiber. We applied the reduced graphene oxide fiber to electrode for the electron emission. The emission current was 1.0 mA and the field enhancement was 4.97×103. It shows that the reduced graphene oxide fiber would be applicable as a material for electron emission.
