A facile synthesis route is described for the preparation of a gold–polyaniline nanocomposite material. The gold nanoparticles were highly dispersed and stabilized throughout the polyaniline fibers that formed a metal–polymer composite material. We measured the temperature‐dependent electrical conductivity of the metal–polymer composite material. The conductivity data are commensurate with the one‐dimensional geometry of the resultant material. The temperature dependence of the Hall coefficient on the composite is in evidence of a possible contribution of a charge carrier deficit and a temperature‐dependent mobility in this material.
