Conducting polypyrrole films with p-toluenesulphonate, perchlorate and tetrafluoroborate dopants were aged at elevated temperatures in oxidizing and inert environments. Their decline in electrical conductivity was analysed using a first-order decay model. Films were also examined by X-ray photoelectron spectroscopy, differential scanning calorimetry, thermogravimetric analysis and scanning electron microscopy. Changes in polymer morphology, degree of oxidation and dopant integrity were determined.
