All-Craphene Core-Sheath Microfibers for All-Solid-State,Stretchable Fibriform Supercapacitors and Wearable Electronic Textiles

摘要

Flexible graphene fiber (GF) stands for a new type of fiber of practical importance, which integrates such unique properties as high strength, electrical and thermal conductivities of individual graphene sheets into the useful, macroscopic ensembles. GFs possess the common characteristics of fibers like the mechanical flexibility for textiles, while maintaining the uniqueness such as low cost, light weight, and ease of functionaliza-tion in comparison with conventional carbon fibers. Due to the extraordinary challenge to assemble two-dimensional (2D) microcosmic graphene sheets with irregular size and shape into macroscopic fibrillar configuration, however, the success in fabrication of neat graphene fibers only comes true recently.
