Polyaniline Nanotubes Doped with Sulfonated Carbon Nanotubes Made Via a Self‐Assembly Process

Abstract

Sulfonated multiwalled carbon nanotubes (MWNT‐(OSO 3 H) n ) can act simultaneously as a dopant and template for the formation of conducting polyaniline(PANI) nanostructures. By controlling the aniline/MWNT‐(OSO 3 H) n ratio, two kinds of nanotubes—PANI‐coated MWNT‐(OSO 3 H) n nanotubes and PANI nanotubes doped with MWNT‐(OSO 3 H) n (see Figure)—can be obtained.
