DYNAMIC-MECHANICAL BEHAVIOR AND THERMAL-DEGRADATION OF UNDOPED POLYANILINE

Dynamical mechanical spectrometry experiments were performed on undope d polyaniline films to provide some information on the microstructure by the analysis of the molecular motions, A mechanical relaxation loca ted at around 200 degrees C has been related to the polyaniline glass transition. At higher temperature, evidence is given for a thermal deg radation which is attributed to crosslinking reactions as confirmed by thermogravimetry and FT-IR experiments.
