Ternary composite phase change materials (PCMs) towards low phase separation and supercooling: eutectic behaviors and application

Phase Separation through Simultaneous Polymerization and Crystallization for Composite Materials

Phase separation of composite materials through simultaneous polymerization and crystallization

Composite materials have attracted much interest because of the emergent properties originating from the components. A variety of methods have been studied to control the morphology of composites based on noncrystalline polymers and crystalline materials. However, it is not easy to control complex morphologies, such as segregated sea-island structures, on the submicrometer scale. Polymerization...

Preparation and Characterization of Composite Phase Change Materials Containing Nanoparticles

The phase change thermal control method is now widely used in aircraft thermal protection due to its high energy density, constant temperature control, flexible operation, and many other advantages.1–6 However, thermal conductivity of most current phase change materials is low in phase transition process.7–10 This paper will add high thermal nanoparticles to phase change material in order to en...

Preparation and Supercooling Modification of Salt Hydrate Phase Change Materials Based on CaCl2·2H2O/CaCl2

Salt hydrates have issues of supercooling when they are utilized as phase change materials (PCMs). In this research, a new method was adopted to prepare a salt hydrate PCM (based on a mixture of calcium chloride dihydrate and calcium chloride anhydrous) as a novel PCM system to reduce the supercooling phenomenon existing in CaCl₂·6H₂O. Six samples with different compositions of CaCl₂ were prepa...
