Özet
In this study, palmitic acid (PA) and capric acid (CA) eutectic mixture was encapsulated in polystyrene (PS) capsules as new latent heat thermal energy storage (LHTES) material for building applications. Eutectic composition ratio of the mixture was determined experimentally. Microencapsulated eutectic mixtures (MEEMs) were prepared in homogenized emulsions in 3 different PS/(PA-CA) weight ratios. The synthesis reaction was found complete according to Fourier Transformed Infrared (FT-IR) Spectroscopy. The physical and physicochemical characteristics, thermal endurance limits and operating stability of MEEMs were investigated through differential scanning calorimetry, thermal gravimetry, and thermal conductivity, particle size distribution analysis, scanning electron microscopy, and polarized optical microscopy techniques. The onsets of melting of MEEMs were measured between 13.5 and 17.1 °C as …
