文摘

Micro-encapsulated phase change material (MEPCM) for high temperature applications are achieved. The MEPCM is composed of a stable α-Al2O3 shell and Al-25 wt% Si core. The MEPCM has an effective void inside the core to allow for volume expansion of the PCMs. The MEPCM exhibits excellent durability up to 300 heating and cooling cycles. The heat capacity of the MEPCM is five times higher than that of conventional solid sensible heat storage materials.
