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.
