Abstract

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.

## Abstract **Summary:** An ultrasonic irradiation assisted polymerization method has been used to prepare PANI nanotubes and nanofibers by using different doping concentrations of mineral or organic acids. It has been found that PANI nanotubes can be produced when the concentration of the dopant a
