Abstract: Four electrically conductive polymers were tested for their thermal transport properties to better understand their degradation mechanism with temperature. The samples that were tested were polyaniline polymers doped with varying amounts of nickel and aluminum. It was found that the thermal conductivities increased as the aluminum:nickel ratio increased, and that the thermal conductivity and thermal diffusivity of the samples increased with temperature until they reached a maximum value, and then began to decrease. It was thought that the decrease was due to the presence of defects (dislocation of ions, ion vacancies in the lattice, etc.) in the composites at high temperature.
