Abstract

Nowadays, research and development of phase change materials (PCMs) become popular parallel with the increased importance of thermal energy storage (TES). In this study, n-heptadecane was encapsulated via natural mineral shell magnesium carbonate (MgCO3) and these capsules were coated with silver to enhance the thermal conductivities of capsules. The thermal, physical and chemical properties of MgCO3 and MgCO3@Ag capsules were compared. The morphologies of capsules are seen as bar-shaped. The latent heat capacities of capsules are compatible with the literature while remaining the phase change temperature range. The thermal conductivities of MgCO3@Ag capsules were found higher than MgCO3 capsules at four times. The results show that these new capsules candidates can be used for TES building applications.
