Abstract

A chemical route for the aniline polymerization was performed in order to develop the morphology for rod-like polyaniline powder. The purpose of our research is to obtain a conductive and stable polymer, with a high surface area. The research interest is to implement the polyaniline as conducting polymers in the fuel cell technology, as self catalyst and support for noble metal deposition. The SEM micrograph shows a specific rod-like polymer morphology. The Cyclic Voltammetry test reveals that the obtained polyaniline powder in the rod like-structure is able to perform as self catalyst in the hydrogen and methanol oxidation reactions.
