Evolution of Physical and Electrochemical Properties of Polypyrrole during Extended Oxidation

摘要: The charge storage capacity and electrical conductivity of polypyrrole are followed through regimes chemically reversible irreversible electroactivity. Overoxidation occurs at potentials in excess 0.7 V vs. a saturated calomel electrode (SCE), as demonstrated by cyclic voltammetry thin films. Material loss from polymer films they overoxidized is determined situ quartz microbalance experiments. potential window for electrochemistry compared to that other conducting polymers. Reflectance FTIR thick reveals hydroxyl groups, carbonyls, result overoxidation.
