Abstract: CdS nanoparticles were dispersed in varying quantities into a PVC matrix and the effective thermal conductivities of the produced nanocomposites were investigated at temperatures from 25 to 110C. It was determined that the dispersion of the nanoparticles in PVC caused an increase in thermal conductivity up to 2 wt. % filler concentration when compared to that of pure PVC. When more than 2 wt. % of filler was added to the PVC matrix, the thermal conductivity began to decrease, and the sample containing 8 wt. % CdS nanoparticles was found to have an effective thermal conductivity that was lower than that of pure PVC. Temperature was also found to have an effect on the thermal conductivity. Conductivity was found to increase in all samples until the temperature reached the glass transition temperature. Past this point, the thermal conductivity of each sample became almost constant as temperature increased.
