Özet
A new shape-stabilized composite phase change material (SSCP) was fabricated by using a promising matter, namely n-octadecane (n-OD) having 200–244.00 kJ kg−1 thermal energy storage capacity. For this aim, one step impregnation method was conducted in order to obtain the composite PCM. Nano-sized gamma alumina (γ-Al2O3) was used as the support material that enhances the thermal properties of the smart composite. The obtained composite materials were investigated by thermal analyse and visualization methods in order to determine its thermal energy storage capacity, phase transition temperature, thermal stability, chemical structure and morphology based on the differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy and polarized optical microscopy analyses, respectively. Based on the DSC results, composite SSCP4 which could be obtained by using a composition of n-OD/γ-Al2O3 of 50:50 (mass/%) has highest thermal energy storage capacity (86.00 J g−1) with the suitable transition temperature (18.95–27.40 °C). Moreover, impregnation ratio of n-OD into the porous framework was found to be 39.58 (mass/%) by TGA. Accordingly, the obtained composite PCM can be a promising candidate for low-temperature (18–30 °C) thermal applications which are required to have the favorable phase change temperature and high energy storage capacity with thanks to its good thermal stability and durability performance.
