Abstract:
Graphene fibers, originally made from natural graphite, represent a new kind of carbonaceous fiber firstly reported in 2011. They are one-dimensionally assembled from neat graphenes or functionalized graphenes liquid crystals by wet-spinning. Graphene fibers exhibit good mechanical, electrical, and thermal performance, providing wide applications in fields of conductive fabrics, heat dissipation, and energy storage. By introducing other molecules into graphene fibers, graphene composite fibers with special function can be produced. Nacre mimic graphene composite fibers with layered structure and excellent mechanical properties can be obtained by adding polymer; magnetic or highly conductive graphene fibers can be fabricated by introducing magnetic or conductive nanoparticles. In addition, graphene fibers can be fabricated into flexible devices such as supercapacitors. Here, we reviewed the progress in research of graphene fibers, including the preparation and application of neat graphene fibers and graphene composite fibers. We also gave a perspective on the future of graphene fibers.
