The electron micrograph analysis showed that the well-dispersed nanoribbons were highly oriented along the fiber axis in the electrospun fibers. A low weight fraction of the GONR improved the mechanical properties of the polymer composite nanofiber yarns. In addition, carbonization significantly enhanced the mechanical and electrical properties. At present, the optimization of the GNR/carbon composite nanofibers is not accomplished. It is expected that better physical properties can be attained by optimization of spinning conditions (e.g. spinning solutions containing a higher content of well-dispersed GONR or higher-aspect-ratio ones) and carbonization conditions. The GNR composite (nano-)fibers and textiles could be applied to reinforcements for lightweight composites. ln particular, GNR/carbon composites could be utilized for high-performance electrodes for fuel cells, secondary batteries and supercapacitors, fiber and textile-shaped solar tells, including flexible and wearable electronic devices and implantable medical devices.
