Preparation and Study of Polyethylene Glycol (PEG)/Titanium Dioxide (TiO₂) Phase Change Materials

Abstract:

This paper adopted the general method of sol-gel to prepare a list of PEG/TiO₂ phase change materials (PCMs). The chemical structure of the materials was investigated by FT-IR respectively. The infrared indicate that the materials have good chemical compatibility. The thermal properties of the samples were measured by differential scanning calorimetry(DSC) and thermogravimetry(TG). The surface topography and crystallized behavior of the materials were detected by SEM and XRD. The TG thermographs show the samples can sustain high temperature about 212°C. The DSC measurements display that the phase change temperature of the materials’ range from 52°C to 56°C. The results obtained from experiments show that the phase change materials possesses a good potential as a thermal energy storage material.
