Summary As an energy storage material, microencapsulated phase change materials (MPCMs) have become a research hotspot in recent years due to their unique thermophysical properties. However, this material usually has limitations in terms of its performance, such as low encapsulation efficiency, leakage during phase change, poor cycle stability, and high degree of supercooling. To solve these problems, nanoparticle as‐modified material to improve the performance of MPCMs has attracted the attention of both domestic and overseas scholars. This paper aims to review the research progress of MPCMs modified by nanoparticle from three aspects: preparation, performance, and application. In this paper, the preparation method and principle of nanoparticles used for the modification of MPCMs are first introduced. Then, based on different properties (mechanical properties, thermal conductivity, thermal stability, and supercooling), the research works of nanoparticle‐modified MPCMs in recent years are reviewed. Finally, the practical applications of nanocomposite MPCM in the field of slurry, building, asphalt pavement, and battery thermal management are reported.

“…The selection of coating material is a very important step in the encapsulation process because it may have decisive effect on the functional properties of the final encapsulated product. To ensure true encapsulation, the stability of microcapsules, prolong storage abilities, suitable drug release mechanism and resistance against the harsh environment , the following factors should be considered in the selection of core and shell material [17]:…”

Microencapsulation being an emerging technique has provided effective solution to the challenges faced by pharmaceutical, cosmetic, food agriculture and textile industries to deliver ingredients in their active forms to the target sites. Chitosan is a non-toxic, biodegradable and biocompatible amino polysaccharide which makes it useful for the encapsulation of various active ingredients with positive potential applications. Chitosan coating on food products, for example, gives them protection from possible antimicrobial attacks, antioxidants and extended shelf life. Likewise, its coating on pharmaceutics has valuable applications in preservation dn targeted drug delivery. In this review, we discuss the formation of chitosan, its properties, microencapsulation process, micro-capsular morphologies, selection of core and shell materials in addition to the process of chitosan encapsulation of various active ingredients and their applications in various fields of science and technology.

“…39 A few investigations were conducted about the hydrated salts NePCMs for BTMs. 40 At present, most of the hydrated salt phase change nanocapsules use inorganic materials as shells, 41 resulting in poor cycling stability, while using organic materials as the shell layer leads to a reduction in thermal conductivity. Cycle stability and thermal conductivity are two important parameters for BTMs, which are crucial for ensuring safety and enhancing the heat dissipation efficiency of the power battery.…”

Herein, silicon carbide (SiC)-doped hydrated salt phase change nanocapsules (NePCMs) with enhanced thermal conductivity and nonflammability were synthesized using a simple method for battery thermal management systems (BTMs). The additional amount of SiC played a critical role in the heat capacities of hydrated salt nanocapsules. The resultant phase change nanocapsules have a latent heat of over 145.6 kJ/kg, good encapsulation of around 60%, thermal conductivity of 0.51 W m–1 K–1, as well as good leak-proof property and thermal cycle stability. More importantly, due to the perfect core–shell structure, the hydrated salt nanocapsules exhibited a significant enhancement in corrosion protection and flame-retardant property. High-rate charging test at ambient temperature showed that the NePCMs cooling was able to maintain a low maximum temperature during the melting process and keep the battery temperature within a safe range. In conclusion, the phase change nanocapsules developed in this work may have great promise in the field of safe and high-efficient battery thermal management.
