THERMALLY STABLE NANO-ENCAPSULATED PHASE-CHANGE MATERIAL, METHODS FOR PREPARING THE SAME, AND ITS APPLICATIONS

Abstract: the present invention relates to a nano-encapsulated phase-change material (nano-pcm), its preparation method, and its applications thereof. the nano-pcm includes at least one phase change core material; an inner polymeric shell; and an outer inorganic shell. the outer inorganic shell surrounds the inner polymeric shell. the nano-pcm offers enhanced thermal stability, efficient heat transfer, and improved dispersion in materials like fabrics and plastics due to its small size and large surface area. it provides thermal regulation for various products, such as clothing and packaging, by storing and releasing energy to buffer temperature fluctuations. additionally, nano-pcm outperforms micro-pcm in thermal stability, mechanical performance, and lifespan, making it ideal for high-temperature processes and multiple thermal cycles.
