“…Steel cans can produce stress cracking corrosion after long exposure and can be mitigated by adding corrosion inhibitors. Alkan et al 90 studied the thermal properties of two salt hydrates (Na 2 SO 4 ·10H 2 O and CaCl 2 ·6H 2 O) encapsulated with a hydrophilic polymer PVA. The PVA polymer and salt hydrates taken in the ration of 1:10 and then stirred to maintain homogeneity.…”

Salt hydrates are one of the most common inorganic compounds that are used as phase change material (PCM). These are available for a wide range of phase transition temperature for thermal energy storage (TES) application. They have some most desired properties for TES applications like high latent heat value, good thermal conductivity, nonexpensive, and were nonflammable. Besides these, due to the undesirable properties like phase segregation, supercooling, and corrosion to the containers, this PCM not recommended for TES application. To mitigate these issues and to make salt hydrates suitable in TES application, much research has been carried out in past years. This main highlight of this article is to provide a comprehensive overview of the use of salt hydrates, their applications and summarize the research outcomes reported by various researchers to every issue for its TES application. This summarized information will be useful to those who are interested to work on this research area. Along with this literature focuses on the advantages, disadvantages, and mechanism of salt hydrates for TES system during its thermal cycle process.

“…while polymer composites based on inorganic salt hydrate PCMs have been much less studied. Even though several directions have been investigated to entrap SSD in polymers such as polyvinylpyrrolidone (PVP), poly(vinyl alcohol) (PVA), dextran sulfate sodium (DSS), and silica-based polymer, − the effect of polymer addition such as the role of chemical functionality and viscoelasticity on the stability and energy performance of PCM is not yet fully understood.…”

This study reports on the use of sodium alginate to effectively stabilize sodium sulfate decahydrate (Na2SO4·10H2O, SSD) based phase change material (PCM) for application as a thermal energy storage material. Alginate/SSD composite PCMs were prepared by blending SSD with different concentrations of alginate polymer. The resulting composite PCMs demonstrate high phase change enthalpy ∼160 J/g and extended cycling stability compared to existing PCM composites. The analysis carried out by optical microscopy, X-ray scattering, and periodic density functional theory (DFT) calculations demonstrated that the stabilization effect was caused by the interplay between ionic and hydrogen bond interactions between the alginate and SSD. Additionally, the variation in mechanical properties of PCM composites with polymer concentrations made it possible to formulate a composite that maintains stable performance after 3D printing. The advanced properties make this composite a promising candidate for application as a thermal energy storage material.
