Sulfonated multiwalled carbon nanotubes (MWNT-(OSO3H)n) can act simultaneously as a dopant and template for the formation of conducting polyaniline(PANI) nanostructures. By controlling the aniline/MWNT-(OSO3H)n ratio, two kinds of nanotubes—PANI-coated MWNT-(OSO3H)n nanotubes and PANI nanotubes doped with MWNT-(OSO3H)n (see Figure)—can be obtained.
