Air exposure followed by hydrochloric acid treatment restores the neutral pristine state of the nanotubes. Spinning of the polyelectrolyte nanotube solutions into polyvinylalcohol solutions produces composite carbon nanotube/polyvinylalcohol fibres, the properties of which are compared to those of fibres obtained from sodium dodecyl sulfate aqueous dispersions.
