▎ 摘　　要

NOVELTY - Manufacture of graphene fiber involves preparing a graphene oxide dispersion with several graphene oxide sheets are dispersed, spinning the dispersion into a coagulation bath containing ammonium thiocyanate to produce a graphene oxide gel fibers, and heat-treating the graphene oxide gel fibers. USE - Manufacture of graphene fiber. Uses include but are not limited to super capacitor, sensor, battery, actuator, touch panel, flexible display, high efficiency solar cell, heat-dissipating film, coating material, seawater desalination filter, and secondary battery. ADVANTAGE - The method enables manufacture of graphene fiber has excellent electrical conductivity characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene fiber, which comprises doped nitrogen and sulfur, and at least partially reduced graphene oxide fibers.
