Overoxidation of Intrinsically Conducting Polymers

Intrinsically conducting polymers may undergo significant changes of molecular structure and material properties when exposed to highly oxidizing conditions or very positive electrode potentials, commonly called overoxidation. The type and extent of the changes depend on the experimental conditions and chemical environment. They may proceed already at much lower rates at lower electrode potentials because some of the processes associated with overoxidation are closely related to more or less reversible redox processes employed in electrochemical energy conversion and electrochromism. These changes may be welcome for some applications of these polymers in sensors, extraction, and surface functionalization, but in many cases, the change of properties affects the performance of the material negatively, contributing to material and device degradation. This report presents published examples, experimental observations, and their interpretations in terms of both structural and of material property changes. Options to limit and suppress overoxidation are presented, and useful applications are described extensively.

A cobalt oxide nanocluster/overoxidized polypyrrole composite film electrochemical sensing interface was fabricated by two step electrochemical method. The electrochemical properties and electrocatalytic activity of the resulting modified electrode were also studied carefully. The results showed that this modified electrode exhibited good stability, good anti‐interference ability, as well as high electrocatalytic activity to the oxidation of glucose. The linear range for the amperometric determination of glucose was 2.0×10−7–2.4×10−4 mol L−1 and 2.4×10−4–1.4×10−3 mol L−1 with a detection limit of 5.0×10−8 mol L−1 (S/N=3), respectively. The sensitivity was 1024 µA mM−1 cm−2.
