Abstract: Metal doping of a polypyrrole matrix was carried out. Nickel and Cobalt were the two metals that were used in this study, and three samples were prepared, one containing 100% Co, one containing 50% Co and 50% Ni, and finally, one containing 100% Ni. The effective thermal conductivity and thermal diffusivity were evaluated, and it was determined that metal doping of the polymer matrix resulted in increases in both the thermal conductivity, and the thermal diffusivity. The sample containing 100% Ni was found to have the largest increase in thermal conductivity. The authors suggest that this is due to the fact that nickel has a higher metal character than cobalt.
