This article aimed to analyze the abilities of self-assembled microcapsules containing calcium carbonate shells and paraffin-based binary cores to act as thermal energy storages. The thermal properties of the microcapsules, such as thermal conductivity and phase change properties, were obtained using the transient plane source (TPS) method and analyzed using an instrument. It was found that the thermal conductivity of the microcapsules was enhanced due to their highly thermally conductive ...
