Abstract

An in situ one pot synthesis route is described for the preparation of a gold-polyaniline nanocomposite material by polymerization of aniline hydrochloride using HAuCl4 as the oxidant. The resultant composite material was characterized by various techniques. The temperature-dependent electrical conductivity values were supportive of a thorough dispersion of metallic conducting centres and the interpretation is commensurate with the one-dimensional geometry of the composite material. The temperature dependence of the Hall coefficient of the gold-polymer composite is evidence of a possible contribution of a charge carrier deficit and a temperature-dependent mobility in this material.
