Highstrength carbon nanotube fibrelike ribbon with high ductility. Carbon nanotube cnt fiber is an important onedimensional macroscopic assembly material with comparable mechanical performance and much richer functionalities as compared with carbon fibers. Supertough carbonnanotube fibres these extraordinary composite fibres can be woven into electronic textiles. Carbon nanotubes cnt combine the best properties of polymers, cfs and metals, resulting. A carbon nanotube fiber is formed by interlocking carbon nanotubes that. Recent progress in this direction includes the development of fiber based batteries and capacitors and even some examples of such fibers incorporated into prototype textiles. Per weight, the energy needed to break these fibers is. By lowering the concentration of nanotubes in the gas phase, through either reduction of the precursor feed rate or increase in carrier gas flow rate, the density of entanglements is reduced and the cnt aerogel can thus be drawn up.
