Good environmental stability, High degree of processability and interesting redox properties associated with its chain heteroatom, polyaniline (PANI) has been one of the most extensively studied conducting polymers during the past ten years. The present review attempts for the first time to summarize the explicit and quantitative dealings with the various intrinsic oxidation states of PANI and its synthesis, Characterizations, Development and applications of polyaniline derivatives that have been made during the past decade. The paper includes the advantages of some selected studies carried out on polyaniline and polyaniline Nobel metal composites and the superiority of Polyaniline. Details are provided of the different methods used for the synthesis of PANI along with mechanisms, theoretical studies and number of special methods used to obtain a nanostructured PANI. A detailed discussion on the mechanism of electrical conduction in PANI and the factors those influence the conductivity of PANI is also included. Finally, the progress towards technological applications is evaluated.
