Summary: Polyaniline (PANI)/Au composite nanotubes and nanofibers are synthesized through a self‐assembly process in the presence of camphorsulfonic acid and hydrochloric acid, as dopants, respectively. The PANI/Au composites are characterized by FT‐IR, UV‐vis, and thermogravimetric analysis to verify the incorporation of the Au nanoparticles and determine the Au content. Structural characterization is performed using SEM, TEM and X‐ray diffraction. The presence of the Au nanoparticles results in an increased conductivity and improved crystallinity of the PANI. The self‐assembly method employed here is a simple and inexpensive route to synthesize multifunctional nanotubes and nanofibers and could be extended to prepare other inorganic nanoparticle/PANI composites.TEM image of PANI/Au nanotubes.
