Dsc Analysis Of Nano-Enhanced Monobasic And Binary Solid-Solid Phase Change Materials For Thermal Storage

Solid-Solid PCMs are latent energy storage substance that can absorb, store and release a substantial amount of thermal energy. Since polyalcohols have low thermal properties, nanoparticles are added to enhance these properties. In this study solid-solid NPG, TAM and binary PCM along with different mass percentage (0.1%, 0.5% and 1%) of aluminium oxide (Al2O3) nanoparticle is evenly dispersed using a low energy ball mill. DCS tests were performed on each sample at 10 degrees C/min heating rate to investigate its thermal properties. It can be observed that the addition of nanoparticles tends negligible effect on transition temperature and latent heat of enthalpy. The transition temperatures for NPG, TAM and binary PCMs before thermal cycling were 51.86 degrees C, 138.5 degrees C and 45.76 degrees C, respectively. Also, no significant changes were observed for transition temperatures after thermal cycling.
