However, leakage problem of PCM during solid–liquid change process limits its application to some extent [10].
To overcome this problem, shape stabilization supports are introduced to fabricate form-stable composite PCM.
Stabilization supports of PCM usually include microencapsulation containers,
e.g. polymer microencapsulation shells, and porous materials, such as expanded graphite, carbon foam, metallic foam, perlite, diatomite, vermiculite, attapulgite and clay minerals [1–15].
