A comprehensive study of thermally treated polyaniline in its emeraldine salt form is presented here.
It offers an understanding of the thermal stability of the polymer.
Emeraldine salt was prepared by a novel emulsion polymerization pathway using dodecylbenzene sulfonic acid and sulfuric acid together as dopants.
The effect of temperature and heating rate on the degradation of this emeraldine salt was studied via thermogravimetric analysis.
The thermally analyzed sample was collected at various temperatures, that is, 250, 490, 500, and 1000°C.
The gradual changes in the structure of the emeraldine salt were followed through cyclic voltammetry, Fourier transform infrared spectroscopy, and ultraviolet-visible spectroscopy.
Results demonstrate that emeraldine salt shows high thermal stability up to 500°C.
This is much higher working temperature for the use of emeraldine salt in higher temperature applications.
Further heat treatment seems to induce deprotonation in emeraldine salt.
Cyclic voltammetry and ultraviolet-visible spectroscopy revealed that complete deprotonation takes place at 1000°C where it loses its electrical conductivity.
It is interesting to note that after the elimination of the dopants, the basic backbone of emeraldine salt was not destroyed.
The results reveal that the dopants employed have a stability effect on the skeleton of emeraldine salt.
