Abstract:
Nanotube fibers with diameters ranging between 10 and 100 microns were produced by a simple spinning process. These fibers were studied by x-ray scattering--a technique that allows good visualization of the composition as well as the alignment of the constituents. The fibers were found to be composed of bundles of single wall carbon nanotubes, poly(vinyl alcohol) polymer chains, graphitic objects, and Ni-based particles. The nanotubes and poly(vinyl alcohol) chains were preferentially oriented along the fiber axis.
