Charge transport property of one-dimensional gold-polyaniline composite networks

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.
