pH-controlled synthesis of sustainable lauric acid/SiO2 phase change material for scalable thermal energy storage

Abstract Lauric acid (LA) has been recommended as economic, eco-friendly, and commercially viable materials to be used as phase change materials (PCMs). Nevertheless, there is lack of optimized parameters to produce microencapsulated PCMs with good performance. In this study, different amounts of LA...
