Abstract: Phase change materials (PCMs) are becoming increasingly important in the field of thermal energy storage. In this study, conductive fillers were added to wax- and polyethylene-based PCMs to improve their thermal conductivity. A Thermal Constants Analyser measured the thermal conductivity of the PCMs using the transient plane source (TPS) method. Results indicated that both nanoparticles improved thermal conductivity, but a lower concentration of expanded graphite improved conductivity more than normal Zimbabwean graphite.
