Abstract
In the present study, a novel phase change material polyethylene glycol (PEG) / titanium dioxide (TiO2) composite was prepared and characterized by DSC, FT-IR, SEM and WAXD. The melting temperature and latent heats of PEG/ TiO2 was determined using differential scanning calorimeter (DSC). The interactions between PEG and TiO2 were analyzed by Fourier transform infrared (FT-IR) spectroscopy. In the form-stable blends, PEG acted like phase change material when the TiO2 served as supporting material. SEM and WAXD tests were performed to investigate the crystalline morphology. PEG/ TiO2 composite were proven a good polymeric phase change heat storage material.
