A change in the character of the time dependence of resistivity at fixed temperature was observed when the temperature of ageing exceeded 85 °C. This observation is reflected in the FTIR spectroscopic measurements on the aged samples. The FTIR spectral variation may be explained by a conformational transition of the polymer chain at about 85 °C. The fact that a transition has been found with deprotonated samples indicates that this feature is an inherent property of polyaniline.
