Abstract

A novel method called melt coaxial electrospray was used to produce phase change material (PCM) microcapsules with sodium alginate as the shell and n-nonadecane as the core. The effect of production parameters on microcapsule size and structure was studied. The microcapsules were characterized using optical microscopy and Fourier transform infrared (FTIR) spectroscopy. The thermal behavior of PCM microcapsules was measured by differential scanning calorimetry (DSC). The results of FTIR and DSC confirmed the successful melt coaxial electrospraying of PCMs. Careful control of production parameters yielded spherical PCM microcapsules with diameter lower than 100 mm and 56 ± 5% encapsulation ratio.
