Polyethylene Glycol Based Form Stable Composite Phase Change Material: A Review

Abstract

Abstract In the present study polyethylene glycol based form stable composite phase change materials have been reviewed. Due to different molecular weight of polyethylene glycol, it contains different melting temperature. So, it can be used at various engineering applications. But, less thermal conductivity and leakage during phase transformation hampers the utilization of polyethylene glycol. To overcome these huddles various researchers develops form stable composite kind of phase change material with the incorporation of porous material and thermal conductivity enhancing material. Thermal, physical and mechanical properties of the composite phase change materials were investigated by the different authors. A number of results indicated that with addition of different form stabilized material the thermal, chemical and mechanical properties have been improved.
