Exploring the encapsulation and analysis of eutectic salt through theapplication of silicon-based agents

This study explores the microencapsulation of a eutectic phase change material (PCM), specificallya blend of sodium phosphate dodecahydrate (Na۲HPO۴·۱۲H۲O) and sodium carbonate decahydrate(Na۲CO۳·۱۰H۲O). Tetraethyl orthosilicate (TEOS) and (۳-Aminopropyl)triethoxysilane (APTES)were employed as silica precursors in an interfacial polymerization method, augmented by the solgelprocess. The SEM results confirmed the efficacy of the microencapsulation, showcasing uniformand intact encapsulation of the materials. DSC results showed that the synthesized microcapsuleshave melting temperature and enthalpy of ۵۱.۶ °C and ۵۵.۸ J/g.
