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.

Organic shell material and phase change material (PCM) have low thermal conductivity, which reduces the heat absorption and release rate of microencapsulated phase change materials (MEPCMs). Boron nitride nanosheets (BNNSs) with high thermal conductivity can not only stabilize the oil phase as the Pickering emulsifier but also improve the thermal conductivity of MEPCMs as one of the shell components, thus facilitating the heat conduction in the microcapsule system. Herein, MEPCM with paraffin wax (PW) as the core material and polystyrene (PS) modified by BNNSs as the shell material (PW@PS/BNNS MEPCMs) are synthesized via Pickering emulsion polymerization. The structure of PW@PS/BNNS MEPCMs can be regulated by tuning the PW and BNNS contents, to achieve high latent heat and thermal conductivity. In comparison to pure PW, the thermal conductivity of MEPCMs−5 wt % BNNSs increases by 63.76% at 25 °C. The PW@PS/BNNS powder possesses a latent heat capacity of 166.3 J/ g, corresponding to a high encapsulation ratio of 80.77%. These properties endow the prepared MEPCMs with excellent thermal regulation properties. We also propose the formation mechanism of PW@PS/BNNS MEPCMs via Pickering emulsion polymerization for the first time, which will guide the MEPCM fabrication toward a reliable direction.
