Abstract [en]

This work aims at preparing a novel form-stable composite phase change material (FSPCM), by loading stearic-capric acid (SA-CA) in porous nanoceramics which are employed as the supporting materials. The morphology and microstructure, chemical compatibility, thermal properties and thermal stability are analyzed. The results indicate that the prepared FSPCM freezes at 24.56 degrees C with latent heat capacity of 73.92 J/g and melts at 22.50 degrees C with latent heat capacity of 76.40 J/g. The as-prepared composite is demonstrated to reveal good physicochemistry stability and an acceptable absorption ratio. Moreover, the thermal conductivity of FSPCM is nearly 7 times higher than that of pristine PCM.
