AB  - The determination of conducting polymer’s thermal properties is essential in engineering processes
and design. Thermal diffusivity is one of the important thermal properties in non-steady state situations. This
fundamental knowledge is useful in the development of processes and control, selection of materials and
prediction of end use properties in many engineering process and design. In this research, laser flash technique
is employed to determine the thermal diffusivity of Polypyrrole and Polypyrrole/Bismuth Oxide conducting
polymers. Measurements were carried out from room temperature up to 420 K. It was observed that the presence
of secondary doping agent of bismuth oxide enhanced the thermal properties of polypyrrole conducting
polymer.
