N2 - Microencapsulated phase change materials were prepared by the interfacial polymerization method with polyurethane resin as the shell and disodium hydrogen phosphate dodecahydrate as the core. The factors which affect the diameter distribution, surface morphology and thermal properties of microencapsules were investigated by the means of SEM, DSC and TG. The results show that the diameter distribution is uniform and the microencapsules have high compactness. The particle size is centralize with the stirring rate of 8000r/m and emulsifying time for 30 minutes. The DSC results show that the melting point of the phase change material does not have much change and phase change thermal storage is obvious.
