文摘

Thermal conductivity of eicosane-based phase change materials was enhanced by suspending silver nanoparticles. Three different solidification routes, namely ice-water bath, room temperature and oven solidification were tested. The oven solidification route samples exhibited the highest values while the ice-water samples showed the least increase. For loadings greater than 2 wt%, thermal conductivity varied non-monotonically with weight fraction of nanoparticles. A decrease in the latent heat and the melting point of the samples was observed as the additives loading increased.
