Abstract
This work presents the preparation of microencapsulated phase change material (MPCM) of lauryl alcohol by using melamine formaldehyde (MF) as shell material. The microstructure, size, and surface morphology of MPCM were analyzed through microscopic analysis, confirming spherical structure and smooth surface. The thermal properties of the MPCM were studied using calorimetric and gravimetric analysis. The melting point and latent heat of fusion of the prepared MPCM were 20.4 °C and 90.53 Jg1, respectively. MPCM exhibits good thermal stability up to 175 °C without decomposition. Furthermore, the Fourier transform infrared (FT-IR) spectroscopy results showed no chemical reaction between the core phase change material (PCM) and shell material. The leak test proved that the phase change occurs inside the microcapsules without leakage. These obtained results confirm that the prepared MPCM is suitable for thermal energy storage material.
