Popis: In this study, the microcapsules containing binary alkane-alcohol organic eutectic of mixed n-tetradecane and 1-dodecanol (TD-DD) phase change materials as the core and poly (methyl methacrylate)(PMMA) as the shell were prepared by emulsion polymerization reaction. The microcapsules were characterized by using DSC, SEM, FT-IR and TG. The results of DSC test showed that melting and freezing temperatures of the microcapsules are-6.136 °C and 5.203 °C, and total latent heat value are-82.522 J/g and 77.632 J/g, respectively. The SEM and FT-IR analyses indicated that PMMA shell has successfully encapsulated TD-DD. The TD-DD and the microcapsules exhibited in spherical shape. Additionally, the TG test showed that the thermal stability of TD-DD was increased after encapsulation.
