Effect of Iron Oxide Nanoparticles on the Thermal Properties of Octadecane Paraffin-based Phase Change Materials

Thermal energy storage technology is the one of inventions for managing and storing the thermal energy in materials during phase change transition. To develop materials for sustainable thermal energy storage, this study uses octadecane paraffin contained carbon atom 18 atoms from the hydroprocessing of palm oil. However, the thermal properties of octadecane paraffin has limitations for use at high temperatures. Therefore, octadecane paraffin were enhanced by additions of iron oxide nanoparticles (IONPs) various of 0.1, 0.3 and 0.5%wt. as monoacylglycerols (MAGs), used as a surfactant to support the dispersion of the IONPs. The effect of IONPs addition of octadecane paraffin are investigated by using differential scanning calorimetry (DSC) and presented the melting temperature of octadecane paraffin shift to high temperature with increasing IONPs content. Thus, IONPs addition can be used to improve the thermal properties of octadecane paraffin to operate at high temperatures.
