“…It is worth noting that mechanical properties are an important factor affecting the application prospects of MEPCMs. [126][127][128][129] MEPCMs with PDA and CNTs shells were prepared by Sun et al [130] The excellent mechanical strength of the MEPCMs with double shells could ensure that the MEPCMs did not leak after 500 thermal cycles, thus improving the thermal-storage performance of the MEPCMs. The effect of poly(methylhydrosiloxane) (PMHS) on the mechanical properties of n-octadecane@silicone MEPCMs was investigated by Guo et al [131] The results showed that the MEPCMs could withstand a maximum pressure of 25 MPa when the PMHS content was 9 wt%.…”

The leakage‐prone disadvantage of pure phase change materials (PCMs) has hampered their practical application, and the encapsulation technology of PCMs has been favored for its ability to mitigate leakage. Combining large solar reserves with energy storage technology can increase the utilization of renewable energy and broaden the application of microencapsulated phase change materials (MEPCMs) in the field of solar energy. First, the fabrication technologies of MEPCMs, which include physical, chemical, and physical–chemical methods, have been comprehensively elaborated in this article. Second, the characteristics of different methods are also summarized. Then, the influences of MEPCMs properties on their thermal storage capacity have been clarified. This work shows the supercooling, phase separation, mechanical properties, encapsulation efficiency, and photothermal conversion performance of MEPCMs. Modification of MEPCMs by metal materials and their oxides, carbon, and semiconductor materials to improve the light absorption capacity. In addition, two‐dimensional materials such as MXene have been widely used to improve the photothermal properties of MEPCMs. Finally, the applications of MEPCMs in the construction, slurry, textile, and food industries are discussed. This work can provide some useful guidance for the optimization strategies of the photothermal conversion performance and practical applications of MEPCMs.

“…Organic-inorganic hybrid shells can combine the high inherent thermal conductivity of inorganic materials and the toughness of polymer shells, and achieve a high thermal conductivity, permeability resistance and thermal stability of MEPCMs. Therefore, the organic-inorganic hybrid shell exhibit promising potential in next-generation shell materials of MEPCMs [ 38 , 102 ]. It can be expected that the incorporation of inorganic nanofillers in organic shells can endow MEPCMs with high thermal conductivity and some unique properties [ 103 , 104 , 105 , 106 , 107 , 108 ].…”

Phase change materials (PCMs) have been extensively utilized in latent thermal energy storage (TES) and thermal management systems to bridge the gap between thermal energy supply and demand in time and space, which have received unprecedented attention in the past few years. To effectively address the undesirable inherent defects of pristine PCMs such as leakage, low thermal conductivity, supercooling, and corrosion, enormous efforts have been dedicated to developing various advanced microencapsulated PCMs (MEPCMs). In particular, the low-dimensional thermally conductive nanofillers with tailorable properties promise numerous opportunities for the preparation of high-performance MEPCMs. In this review, recent advances in this field are systematically summarized to deliver the readers a comprehensive understanding of the significant influence of low-dimensional nanofillers on the properties of various MEPCMs and thus provide meaningful enlightenment for the rational design and multifunction of advanced MEPCMs. The composition and preparation strategies of MEPCMs as well as their thermal management applications are also discussed. Finally, the future perspectives and challenges of low-dimensional thermally conductive nanofillers for constructing high performance MEPCMs are outlined.

“…Renewable energy sources, including solar energy, are considered ideal alternatives to traditional fossil fuels, but there is a mismatch between supply and demand in time/space [5] . To satisfy various application environments, a suitable thermal energy storage system is required to store it temporarily and use it when needed [6] . Latent heat storage based on phase change materials (PCMs), which are capable of absorbing/releasing thermal energy through the phase change behavior, proved to be effective [6,7] .…”

Microencapsulation of paraffin with melamine formaldehyde shell (Pn@MF) shows the drawbacks of low thermal conductivity. Hence, we constructed SiO2 shells on Pn@MF phase change microcapsules by interfacial polycondensation to obtain Pn@MF@SiO2 double‐shelled microcapsules. The effect of tetraethoxysilane (TEOS) contents on the performance of Pn@MF@SiO2 was discussed in detail. As the TEOS contents increased, the thermal conductivity of Pn@MF@SiO2 gradually increased, reaching up to 0.376 W m−1 K−1. The Pn@MF@SiO2 have exhibited superior leakage‐proof properties and thermal reliability through double‐shelled protection, and the highest reduction in leakage rate reached 45.06 % compared to Pn@MF microcapsules. The Pn@MF@SiO2‐3 with the lowest enthalpy still exhibit a latent heat storage capacity of more than 176 J/g, which displayed outstanding latent heat storage/release capability and good anti‐permeable property.
