Thermal Analysis of Chemcially Synthesized Polyemeraldine Base

摘要

Thermal characteristics of chemcially synthesized polyemeraldine base have been experimentally investigated using differential scanning calorimetry and thermogravimetric analysis (TGA), UV-bisible, and Fourier transform IR techniques, respectively. Results of the TGA measurements have revealed that the chemcially synthesized emeraldine base in thermally stable upto about 400degC. The effect of temperature on time taken for crosslinking in the polyemerraldine base has also been studied. Analysis of reaction kinetics of crosslinking in polyemeraldine base reveals that a pseudo first-order thermodynamic reaction occurs in this conducting polymer.
