Development of Microencapsulated Phase Change Materials

Phase change materials have garnered significant attention in both scientific and industrial spheres, attributed to the pressing need to curtail global energy consumption. The utilization of latent heat energy storage, known for its high energy storage capacity and stable operating temperatures, has piqued considerable interest. However, challenges such as flammability, low thermal conductivity, subcooling, and phase separation have hindered its widespread adoption. To solve these issues, the implementation of encapsulation techniques has emerged as a transformative solution, offering a versatile range of applications, particularly in temperature regulation within construction settings. This comprehensive chapter provides an extensive overview of the development, methodologies, and characterization of the microencapsulation of phase change materials. The methodology primarily entails enveloping the droplets of phase change materials with a delicate polymeric layer. The findings notably indicate that the microencapsulation process minimally affects the thermal properties of the phase change material, affirming the exceptional thermal stability of the resultant microcapsules. Furthermore, the chapter explores the diverse potential applications of microencapsulated phase change materials across various domains, extending beyond construction to encompass the realms of textiles, food production, and other pivotal sectors. The chapter highlights the transformative potential of microencapsulation as an innovative approach to creating advanced phase change materials. It underscores their remarkable capacity to reshape the landscape of thermal energy storage applications, heralding a promising era of innovation and sustainable energy solutions.
