Figure shows an aniline solution's linear sweep voltammogram (LSV) between 0 and +1.0 V vs SCE. Aniline polymerizes from a potential of +0.8 V vs SCE. Between +0.8 V and +0.9 V, only aniline is oxidized. The electrolyte solution decomposes at potentials greater than +0.9 V, and further overoxidation occurs. We have therefore decided on a potential of +0.8 V for PN synthesis, as in other reports on PN electro-polymerization .
