  • The mica was used as a supporting matrix for composite phase change materials (PCMs) because of its distinctive morphology and structure in this work. Mica-based composite PCMs were prepared by vacuum impregnation method using mica as supporting material and polyethylene glycol (PEG) as phase change material. Fourier transform infrared (FTIR) and X-ray diffraction (XRD) analysis confirmed that the addition of PEG had no effect on the crystal structure of mica, and no chemical reaction between PEG and mica during the vacuum impregnation process, and no new substance was formed. The maximum load of mica stabilized PEG is 46.24%, the phase change temperature of M400/PEG is 46.03°C, and the latent heat values of melting and cooling are 77.75 J g-1 and 77.73 J g-1, respectively. The thermal conductivity of M400/PEG is 2.4 times that of pure PEG. The thermal infrared images indicated that the thermal response of M400/PEG was improved compared with that of pure PEG. The leakage test confirmed that mica could stabilize PEG, and M400/PEG had great form-stabilized property. These results demonstrate that M400/PEG has potential in the field of building energy conservation.
