For TES applications, the thermal stability of solid-solid PCMs is a very signicant parameter due to the negative effect of thermal degradation on the working life of solid-solid PCMs.…”

Synthesis and thermal properties of cross-linked poly(acrylonitrile-co-itaconate)/polyethylene glycol as novel form-stable change material

“…FSPCMs can be prepared by encapsulation of PCM into inorganic materials with porous lamellar structure or polymers with high melting point and so on [12][13][14]. Although inorganic materials can ensure the same macroscopic shape before and after the phase transition, the PCM is easy to loss by migrating to the surface after repeated use.…”

Preparation and properties of polyethylene glycol based semi-interpenetrating polymer network as novel form-stable phase change materials for thermal energy storage

“…The merit of solid-solid PCMs is that no container is needed to seal them, due to that there is no gas or liquid generate during the phase transition. Nevertheless, small latent heat restrict their applications [9,10]. A great variety of solid-liquid PCMs including paraffin wax [11], fatty acids [12], fatty alcohol [13] and polyethylene glycol (PEG) [14] have been developed and applied extensively in the field of LHTES, due to their excellent properties such as high latent heat storage capacity, appropriate phase change temperature ranges, little or no super-cooling, non-toxicity, less or no volume change during phase transition, good thermal stability and so on [15].…”
