The fundamental experiments were performed to establish the operational conditions required toprepare the microcapsules containing paraffin wax as a phase change material PCM and SiCpowder with the interfacial polycondensation reaction. It was investigated how SiC powder affecteda few characteristics of microcapsules such as the diameters of microcapsules, latent heatstorage density, thermal responsibility and supercooling. In the experiment, the concentration ofoil soluble surfactant, the revolution speed of impeller for preparing the O-W emulsion and theadded weight of SiC powder were changed stepwise. The microcapsules containing PCM in whichSiC powder was dispersed could be prepared well and characterized. The diameters of microcapsulesincreased by containing SiC powder and the content of SiC powder could be increased byperforming surface modification of SiC powder. Latent heat storage density decreased with thecontent of SiC powder. Supercooling of PCM and thermal responsibility could be improved to somedegree by containing SiC powder.
