Abstract
Microencapsulation technology is an effective method to enhance the thermal energy storage performance and operational reliability of phase change materials. However, inorganic hydrated salt phase change microcapsules have long faced challenges such as low encapsulation efficiency and insufficient thermal cycling stability due to the high salt concentration and hydrophilic nature of hydrated salts. In this study, sodium acetate trihydrate was employed as the core phase change material. Utilizing a water-in-oil inverse emulsion templating method, hydrophilic monomer diethylenetriamine and flexible PEG were spontaneously triggered to polymerize with hydrophobic monomer isophorone diisocyanate at the oil–water…
