Abstract: Nanocomposites of polyaniline nanofibers reinforced in epoxy were prepared and their ultrasonic velocities, ultrasonic attenuations, and thermal conductivities were measured over a temperature range of 298-373 K. It was found that the ultrasonic velocity decreased with increasing temperature, but increased with increasing concentration of polyaniline nanofibers in the epoxy matrix. These two trends were opposite for the ultrasonic attenuation, and the thermal conductivity was found to increase with increasing temperature as well as with increasing polyaniline nanofiber concentration.
