This study synthesizes microencapsulated phase change materials (MePCM) from industrial waste-derived expanded polystyrene (EPS) nanoparticles using a surfactant-free Pickering emulsion for building applications in hot climates. EPS nanoparticles, synthesized via optimized nanoprecipitation technique with 70 % sonicator amplitude, serve as the MePCM shell with n-eicosane as the core. Characterizations show EPS nanoparticles with diameter of 150 nm and MePCM sizes predominantly around 12μm. MePCMs exhibit melting and solidification enthalpies of 301.4 J/g and 298.5 J/g, respectively, highlighting their potential for integration into building materials for enhancing thermal management of buildings in hot climate.
