THE PREPARATION AND PROPERTIES OF MICROCAPSULE PHASE CHANGE MATERIAL FOR COOL STORAGE
The microcapsule phase change material (MPCM) for cool storage is prepared by complex coacervation method with gelatin and acacia as wall materials, tetradecane (C14H30) as a core material in an emulsion system. The Scanning Electron Microscope (SEM) is used to view the microstructure of the MPCM. The Differential Scanning Calorimeter (DSC) is used to determine the melting temperature, the melting latent heat, the freezing temperature, the freezing latent heat of the MPCM, and the thermogravimetry (TG) is used to determine the thermal stability of the MPCM. The SEM micrograph indicates that the MPCM has been successfully synthesized and the particle size of the MPCM is 1～20μm. The DSC output results display that the melting temperature of the MPCM is 5.792℃, the melting latent heat is 191.919J/g, and the freezing temperature is 2.564℃, the freezing latent heat is 189.173J/g. The TG thermograph shows MPCM can sustain high temperature without broken.
