A review of microencapsulated thermochromic coatings for sustainable building applications

The review covers microencapsulation methods for encapsulating thermochromic leuco dyes, and the incorporation of these microencapsulated thermochromic dyes in smart coatings has been developed, which helps in creating sustainable buildings that use less power for heating and cooling applications. The thermochromic mechanism of leuco dye developer–solvent systems has been elaborated, and the role of each component for the functioning of thermochromic dyes is discussed. The future scope of these dyes in applications involving smart windows and smart coatings for sustainable buildings is consolidated, and their impact on energy consumption has been studied.
