| description | A novel microencapsulated phase change materials for cold energy storage was synthesised through sol-gel means using decanol as phase change material and titanium dioxide (TiO2) as encapsulated material. The micromorphology and composition of microcapsules were observed by field emission scanning electron microscope (FE-SEM), Fourier transformation infrared spectrometer (FT-IR).Using differential scanning calorimeter (DSC) and thermogravimetric analyzer (TGA) thermal properties of microcapsules were characterized. Results of FE-SEM and FT-IR indicated that micro sized decanol droplets were encapsulated with TiO2 to form the well-developed core-shell structure, which was only physical coating between them. Furthermore, the chemical and thermal stability of the microcapsules were improved and the inflammability of the microcapsules was lowered using TiO2 as shell material. The DSC result of the desirable ones melt at 3.87 ℃ with a latent melting enthalpy of 61.12 J·g-1 and solidified at – 1.32 ℃ with a latent solidification enthalpy of 59.54 J·g-1. In general, the prepared microcapsules have potential for cold energy storage. |
