Micro/nanoencapsulated n-nonadecane with poly(methyl methacrylate) shell for thermal energy storage

This paper was aimed to prepare, characterize and determinate of thermal energy storage properties of PMMA/C19 micro/nanocapsules as a novel encapsulated phase change material (M/N-EPCM). The chemical structure of the prepared M/N-EPCM was verified using FTIR spectroscopy method. The analysis results obtained from POM and SEM indicated that the synthesized capsules had virtually spherical-shape. The PSD analysis indicated that the M/N-EPCM capsules had mean diameter of 8.18 μm and the percentage of the capsules with nanosize was 4.90 (v/v). The DSC results showed that the synthesized M/N-PCM had a melting temperature and total latent heat value as 31.23 °C and 139.20 J/g, respectively. It can be also deduced from all results that the synthesized M/N-EPCM had promising thermal energy storage potential due to its good latent heat thermal energy storage properties, thermal durability, thermal reliability, chemical stability, thermal conductivity and phase change reversibility properties.
