Spinning Solid and Hollow Polymer-Free Carbon Nanotube Fibers

Polymer‐free carbon nanotube fibers are spun from aqueous dispersions using a flocculation‐based process that was developed. It produces hollow fibers, folded ribbon fibers, and solid fibers (see Figure). The fibers spun from single‐walled nanotubes exhibit relatively high electrical conductivities...

Description
Summary:	Polymer‐free carbon nanotube fibers are spun from aqueous dispersions using a flocculation‐based process that was developed. It produces hollow fibers, folded ribbon fibers, and solid fibers (see Figure). The fibers spun from single‐walled nanotubes exhibit relatively high electrical conductivities (∼140 S cm–1 at room temperature) and electrochemical capacitances (∼100 F g–1) after annealing. Fiber supercapacitors are made from the spun fibers.
