Al2O3, TiO2 nanoparticles, and carbon nanotubes were added to Iraqi paraffin wax in varying quantities to determine the optimum filler content for the enhancement of thermal conductivity. The thermal conductivity was enhanced by 65 and 40% for samples containing 5 wt. % of Al2O3 and TiO2 nanoparticles, respectively. It was concluded that the addition of these nanoparticles to paraffin wax enhanced the thermal conductivity of the phase change material without sacrificing its ...
