    Abstract

    A method for the direct spinning of pure carbon nanotube fibers from an aerogel formed during chemical vapor decomposition is presented. Fibers based in single-walled carbon nanotube have been successfully produced by conventional spinning from lyotropic solutions in super acids, and such fibers have the high modulus. Polyvinyl alcohol (PVA)-SWCNT composite fibers have a tensile strength of 1.8GPa and remarkable toughness and a strain to failure of 100% in samples that were prestrained by about 20%. The spectrum from direct-spun CNT fibers showed peaks in the 128 to 245 cm-1 wave number that correspond to the single-walled carbon nanotube diameters in the range of 1-2 nm.
