We prepare phase change material microcapsules via an organic phase separation method, adopting eutectic hydrated salt as the core material and composite organic polymers as the shell material. The resulting microcapsules exhibit spherical morphology and core-shell structure with a phase change enthalpy of 131.4 J/g.
In this paper, a comprehensive review has been carried out on PCM microcapsules for thermal energy storage. Five aspects have been discussed in this review: classification of PCMs, encapsulation shell materials, microencapsulation techniques, PCM microcapsules' characterizations, and thermal applications.
Can phase change microcapsules solve the leakage problem of PCM during use?
Preparing microcapsules with core-shell structure by encapsulating phase change materials (PCM) in the shell is considered as an effective method to solve the leakage problem of PCM during use. Herein, a phase change microcapsule (MPCM) based on n-eicosane core and polyurea shell was prepared.
What are phase change materials (PCMs)?
Phase change materials (PCMs) are gaining increasing attention and becoming popular in the thermal energy storage field. Microcapsules enhance thermal and mechanical performance of PCMs used in thermal energy storage by increasing the heat transfer area and preventing the leakage of melting materials.
Do microcapsules improve thermal and mechanical performance of PCMS?
Microcapsules enhance thermal and mechanical performance of PCMs used in thermal energy storage by increasing the heat transfer area and preventing the leakage of melting materials. Nowadays, a large number of studies about PCM microcapsules have been published to elaborate their benefits in energy systems.
