A new type of shape stabilized phase change material (PCM) with good heat storage was produced by intercalating myristic acid (MA) with modifid montmorillonite (MMT). The structure, thermal properties of the composite PCM were determined by X-ray diffraction (XRD), Fourier transformation infrared (FTIR) and Differential Scanning Calorimetry (DSC) analysis technique. In the XRD analysis, expansions of the d spacings in the (001) plane were observed in all samples, indicating that the intercalation of MA in the interlayers of MMT was successfully achieved. The results of DSC indicated that the shape stabilized PCM displayed a high heat capacity (133.6 J.g-1) |
