Abstract: Changes in the various chemical and structural properties of polyaniline (PANI) films effected by interaction with Fenton’s reagent are monitored with electrochemical in situ spectroscopic and surface-sensitive techniques. Starting from a model of possible structural changes caused by chemical attack of species generated by Fenton’s reagent, particular attention is paid to the differences between the compact and highly porous (open) forms of PANI.

Keywords: spectroelectrochemistry – polyaniline – Fenton’s reagent – chemical degradation
