One-step synthesis of electrically conductive polyaniline nanostructures by oxidative polymerization method

A simple, rapid and efficient route to prepare polyaniline nanostructures (PANI-NS) by "one-step chemical oxidative polymerization" method is described. This method possesses advantages in terms of good yield, short reaction time, neat conditions and cost-effectiveness. The morphology of the PANI-NS was investigated by field-emission scanning electron microscopy (FE-SEM). The average diameter of single PANI-NS was calculated to be similar to 376 nm. Results from UV-visible spectroscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis and cyclic voltammetry (CV) reveals the existence of PANI units present in the polymeric nanostructures. Also, electrical conducting property of the PANI-NS was analyzed using four-probe measurement method. (c) 2012 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.
