ABSTRACT: The fundamental experiments were performed to establish the operational conditions required to
prepare the microcapsules containing paraffin wax as a phase change material (PCM) and SiC
powder with the interfacial polycondensation reaction. It was investigated how SiC powder affected
a few characteristics of microcapsules such as the diameters of microcapsules, latent heat
storage density, thermal responsibility and supercooling. In the experiment, the concentration of
oil soluble surfactant, the revolution speed of impeller for preparing the (O/W) emulsion and the
added weight of SiC powder were changed stepwise. The microcapsules containing PCM in which
SiC powder was dispersed could be prepared well and characterized. The diameters of microcapsules
increased by containing SiC powder and the content of SiC powder could be increased by
performing surface modification of SiC powder. Latent heat storage density decreased with the
content of SiC powder. Supercooling of PCM and thermal responsibility could be improved to some
degree by containing SiC powder.
