Polythiophene (PTh) has attracted much attention because of its high electrical conductivity, good thermal stability, ease and high redox activity, stability and good mechanical properties. In the present work, samples of PTh were synthesized by using chemical oxidative polymerisation method with different concentration (0.1-0.3 M) of anhydrous ferric chloride (FeCl3) as an oxidant in aqueous medium at room temperature. The DC electrical conductivity was found in the range of 10-3 Scm-1. In order to understand transport mechanism, temperature dependence of conductivity was investigated. The polymerization was confirmed through FTIR spectroscopy and performing XRD analysis recognized amorphous phase of the samples.
