Abstract : The goal of this work is to develop a prospective cool decorative coating used to store thermal energy with the use of melamine formaldehyde microcapsules containing core of a eutectic mixture of Lauric acid-Myristic acid as a phase change material. Melamine and formaldehyde were reacted in a two-step reaction to create the shell material.The Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), Polarized Optical Microscopy (POM), and Scanning Electron Microscopy (SEM) techniques were used to analyse the microcapsules. LA-MA eutectic, incorporated in the microcapsule (MF-LA-MA), has been found to melt at C with the latent heat of melting 116.2J/g and crystallizes at with latent heat crystallization 114.4J/g. The phase change characteristics of the coated material were observed to improve as the microcapsule loading increased. The thermal energy transfer rate was enumerated in terms of the time taken by the coated panels to attain an equilibrium temperature of 60C. According to Thermogravimetric Analysis (TGA), LA- MA eutectic in the microcapsule has improved thermal stability.

Keywords : Phase Change Material, Thermal Energy Storage, Microencapsulation, Cool Coating.
