Polyethylene glycol (PEG) is a commonly used phase change material for thermal energy storage. It can store amounts of heat in the process of phase transition, whereas the solid-to-liquid transition requires it to be form-stabilized before application.
Phase change materials (PCMs) are ideal solar energy storage materials due to their high latent heat, excellent chemical stability, and high energy storage capacity [4, 5]. PCMs can be classified into three categories: organic, inorganic, and composite phase change materials (cPCMs) according to the chemical property.
