“…Then, they dispersed the composite MPCMs in water, and the obtained PCS had excellent photothermal properties. Xu et al 113 developed paraffin/Cu 2 O/CNT MPCMs via hydrothermal reduction and in‐situ deposition method and produced the PCS with MPCMs and deionized water. It was found that the thermal properties and photothermal conversion efficiency of the PCS were effectively improved with the content of CNTs.…”

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.

Phase change materials (PCMs) are gaining increasing attention and becoming popular in the thermal energy storage field. Microcapsules enhance thermal and mechanical performance of PCMs used in thermal energy storage by increasing the heat transfer area and preventing the leakage of melting materials. Nowadays, a large number of studies about PCM microcapsules have been published to elaborate their benefits in energy systems. In this paper, a comprehensive review has been carried out on PCM microcapsules for thermal energy storage. Five aspects have been discussed in this review: classification of PCMs, encapsulation shell materials, microencapsulation techniques, PCM microcapsules’ characterizations, and thermal applications. This review aims to help the researchers from various fields better understand PCM microcapsules and provide critical guidance for utilizing this technology for future thermal energy storage.

“…Liu et al introduced a microcapsules composite material of dodecyl alcohol as core material and MF resin modified with GO and CNTs as shell material, which not only greatly improved the thermal conductivity of the materials, but also the photothermal conversion performance of the prepared slurry has been greatly improved [25]. In addition, we have successfully prepared paraffin@TiO 2 /GO, and paraffin@Cu-Cu 2 O/CNTs microcapsules, which have greatly improved in terms of photothermal properties as compared to unmodified materials [26,27]. According to the literature, tin dioxide (SnO 2 ) is an inorganic material with high thermal conductivity and good thermal stability [28,29].…”

In this study, In-situ precipitation reaction was used to prepare paraffin@SnO 2 /CNTs composite phase change materials. The paraffin@SnO 2 /CNTs composites material were prepared by using paraffin as a phase change core material, and tin dioxide and carbon nanotubes as composite shell materials. The microstructure, chemical composition and crystal phase structure of the composites were analyzed by Scanning electron microscope (SEM), Fourier infrared spectrum (FT-IR) and X-ray diffraction (XRD). The thermal performance and thermal stability of phase change materials were determined by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The microcapsule has a core-shell structure with a diameter of 2-5 μm. The encapsulation efficiency of the paraffin@SnO 2 /CNTs composite was calculated to be 42.94%. The slurry is formed by dispersing microcapsules in water, which not only greatly improves the specific heat capacity, thermal conductivity, visible light absorption, but also makes the effective receiving efficiency reach 91.79% at 40°C, indicating that it is a promising heat transfer working slurry in the field of Direct Absorption Solar Collectors (DASC) system.
