Electrically conducting composite materials consisting of different weight percentage of iron oxide nanoparticles dispersed in Polyurethane diol/Polycaprolactone were prepared. As a function of temperature between 30-70°C and frequency in the range of 1 kHz to 1000 kHz the dielectric constant and conductivity of polymer nanocomposites were studied. The dielectric constant value increased with increase in temperature and decreased with increase in frequency. Conductivity was found to be in the order of 10 -6 to 10 -5 S/cm and increased with increase in temperature. Cyclic voltammetry investigations revealed that the material has the potential to perform as an alternative catalyst for fuel cell applications.
