Polyethylene glycol di-stearate,as a novelsolid-liquid phase changematerials(PCMs),was prepared from the reaction between PEG200 and stearic acid through thionylchlorided esterification. PEG200双硬脂酸酯固-液相变温度在30℃-35℃,相变焓为95 J/g。
This chapter presents the principles of solid-liquid phase change materials (PCMs). The classifications of PCMs are discussed along with their advantages and disadvantages. PCMs can have problems in regards to incongruent melting, phase separation, subcooling, and low thermal conductivity. Literature ...
Various types of solid–liquid phase change materials (PCMs) have been reviewed for thermal energy storage applications. The review has shown that organic solid–liquid PCMs have much more advantages and capabilities than inorganic PCMs but do possess low thermal conductivity and density as well as ...
Concentrating solar power systems and methods featuring the use of a solid-liquid phase change heat transfer material (HTM). The systems and methods include a solar receiver to heat and melt a quantity of solid HTM. Systems also include a heat exchanger in fluid communication with the solar ...
Phase change materials (PCMs) have been widely used for thermal energy storage systems due to their capability of storing and releasing large amounts of energy with a small volume and a moderate temperature variation. Most PCMs suffer the common problem of low thermal conductivity, being around 0....

Switchable optical transparency is an intrinsic property for solid–liquid phase change materials (PCMs) during phase change processes. However, due to non-transparent porous confinement materials and core-shell structures, the synthesis of shape-stabled PCMs typically sacrifices their switchable optical ...
