Electrochemical Synthesis of Polyaniline Nanoparticles and Nanofibers

摘要

The electrochemical deposition of polyaniline nanofibers and nanoparticles have been investigated on gold electrodes by cyclic voltammetry and their morphology by high resolution scanning electron microscopy and atomic force microscopy. The type and dimensions of the nanostructures obtained depend on deposition conditions such as monomer concentration, scan rate and electrical potential. We have observed that the nucleation and growth steps play a key role on the film growth and its nano-morphology.
