In this study, decanoic acid suitable for thermal energy storage applications was microencapsulated with poly(styrene-co-ethyl acrylate) by emulsion co- polymerization method. Chemical structures, morphological characteristics, and thermal properties of microcapsules and macrocapsules were determined using Fourier Transfer Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), and Differential Scanning Calorimeters (DSC) respectively. The microPCMs and macroPCMs were synthesized successfully and the encapsulation ratio was about up to 65.5 %. As a result, the as-prepared microcapsules show good potentials for thermal energy storage and could be used in many applications.
