“…For modifying the shell material, according to the structure design of shell material, the modification can be also classified into two pathways: The one pathway is to synthesize hybrid shell microPCMs by adding particles to shell material. Li and his coworkers synthesized the phase change microPCMs with polymethylmethacrylate (PMMA)/TiO 2 shell. Because of the addition of TiO 2 , the encapsulation efficiency and melting enthalpy of the microPCMs were increased obviously.…”

Summary In order to enlarge the applications of microencapsulated phase change materials (microPCMs), the novel stearic acid (SA)@graphene oxide (GO)/melamine‐formaldehyde (MF) multifunctional superhydrophobic microPCMs were prepared with the method of condensation polymerization. We have made a systematical study of the effects of GO content on the SA@GO/MF microPCMs. The morphology and chemical composition characterizations showed the successful fabrication of microcapsules. The differential scanning calorimeter (DSC) identified that microPCMs could store latent heat energy. According to the contact angles (CA) measurement, the microPCMs displayed the water contact angle of 160.2°, which possessed the superhydrophobic property. Moreover, the self‐cleaning property of SA@GO/MF microPCMs was demonstrated by designing self‐cleaning experiment. The simulated irradiation experiment showed the good photothermal conversion performance of microPCMs. Owing to photothermal energy conversion performance and superhydrophobicity, multifunctional phase change microcapsules could have vital potentials in energy conversion and self‐cleaning.

“…Compared with pure paraffin, the thermal conductivity of MPCMs improved from 0.304 to 1.322 W/m K after adding 3 wt% Ti 4 O 7 nanoparticles, and the photothermal storage efficiency of MPCMs significantly increased from 24.14% to 85.36%. Li et al 89 employed the Pickering emulsion polymerization to prepare MPCMs with TiO 2 /PMMA hybrid layer and n ‐octadecane. In the action of TiO 2 , the overall thermal conductivity of hybrid shell material was gradually improved.…”

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.

“…In organic-inorganic hybrid shells, inorganic materials can enhance mechanical rigidity, thermal stability, and thermal conductivity, whilst organic materials offer structural flexibility [52]. Shells formed from polymers, such as PMMA and PMF, and doped with SiO 2 or TiO 2 are widely used to encapsulate PCMs [90][91][92][93].…”

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.
