Preparation of Stearic/Montmorillonite Composite as Form-Stable Phase Change Material

Abstract:

A new type of form-stable phase change material (PCM) with good heat storage was prepared by impregnation of stearic acid (SA) into the interlayer of modified 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 interlayer platelet spacing (001 diffraction peak) were observed in all samples, indicating that the impregnation of SA in the interlayer of MMT was successfully completed. The results of DSC indicated that the melting point and latent heat of the form-stable PCM is 63.2 °C and 118.6 J/g, respectively
