Abstract: The specific heat of the emeraldine base form of polyaniline and the emeradine salt of polyaniline has been measured at temperatures between 1.8 and 45K. The experimental results have been interpreted in terms of the contributions from both the crystalline and the amorphous phases characterizing the polymer. Anomaly of the specific heat, which is much larger than that expected from the Debye theory, has been successfully explained by the phonon-fracton model at low temperatures. The electronic specific heat has not been observed from the present data.
