Polyaniline nanobelts, flower-like and rhizoid-like nanostructures by electrospinning

Nanobelts, flower-like and rhizoid-like nanostructures of pure polyaniline (PANI) doped with sulfuric acid or hydrochloric acid were prepared via electrospinning by using a coagulation bath as the collector after optimizing the fabrication parameters. The morphologies of these nanostructures were characterized by scanning electron microscope (SEM). The possible formation mechanisms were discussed.
