Abstract: Nanocomposites are formed by combining conducting polymers and inorganic nanoparticles. In this study, nanocomposites of Ni-Zn ferrite were tested to determine the variation in their thermal properties. A thermal analyzer was used to measure thermal conductivity and thermal diffusivity of the composites using the transient plane source (TPS) method over a temperature range of 30 to 140°C. Results indicate that thermal conductivity and thermal diffusivity of Ni-Zn ferrites in a copolymer matrix of aniline formaldehyde depend both on temperature and concentration of zinc in the composite.
