“…Typically, one way was employed to prepare the multi-functional MEPCMs, for instance, the functional NPs ferric oxide (Fe 2 O 3 ), titanium dioxide (TiO 2 ), zinc oxide (ZnO), metal–organic frameworks (MOFs), and were embedded into the polymeric shell, or the functional inorganic shells like TiO 2 , cuprous oxide (Cu 2 O), tin dioxide (SnO 2 ), and cadmium sulfide (CdS) were directly used for the shell to achieve the UV shielding, fluorescent, photothermal conversion, photocatalysis, antibacterial, and thermal conduction, etc. [ 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ]. In our previous work [ 29 ], a kind of MEPCM with TiO 2 /PDVB hybrid shell was fabricated by Pickering emulsion polymerization; nevertheless, the use efficiency of single functional TiO 2 NPs in the MEPCM is relatively low, nonfunctional PDVB shell could not achieve a synergetic combination of NPs and shell for further improving the multi-functionality especially the photocatalysis.…”

A novel type of bi-functional microencapsulated phase change material (MEPCM) microcapsules with thermal energy storage (TES) and carbon dioxide (CO2) photoreduction was designed and fabricated. The polyaniline (PANI)/titanium dioxide (TiO2)/PCN-222(Fe) hybrid shell encloses phase change material (PCM) paraffin by the facile and environment-friendly Pickering emulsion polymerization, in which TiO2 and PCN-222(Fe) nanoparticles (NPs) were used as Pickering stabilizer. Furthermore, a ternary heterojunction of PANI/(TiO2)/PCN-222(Fe) was constructed due to the tight contact of the three components on the hybrid shell. The results indicate that the maximum enthalpy of MEPCMs is 174.7 J·g−1 with encapsulation efficiency of 77.2%, and the thermal properties, chemical composition, and morphological structure were well maintained after 500 high–low temperature cycles test. Besides, the MEPCM was employed to reduce CO2 into carbon monoxide (CO) and methane (CH4) under natural light irradiation. The CO evolution rate reached up to 45.16 μmol g−1 h−1 because of the suitable band gap and efficient charge migration efficiency, which is 5.4, 11, and 62 times higher than pure PCN-222(Fe), PANI, and TiO2, respectively. Moreover, the CO evolution rate decayed inapparently after five CO2 photoreduction cycles. The as-prepared bi-functional MEPCM as the temperature regulating building materials and air purification medium will stimulate a potential application.

“…The modification of shell material by TiO 2 nanoparticles can improve the thermal stability of MPCM. Daou et al 94 used paraffin as core and UF resin doped with metal oxide nanoparticles (Fe 2 O 3 , ZnO, and TiO 2 ) as shell. TGA results indicated that Fe 2 O 3 , ZnO, and TiO 2 nanoparticles hinder the decomposition of shell material.…”

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.

“…As an important type of thermal energy saving materials, phase change materials (PCMs), which can store and/or release lots of thermal energy during its solid-liquid phase transition, are efficient media for latent heat thermal energy storage (LHTES) owing to their high energy storage capacity and small temperature variation. Their broad applications in building, [1,2] solar energy utilization, [3][4][5][6] intelligent textiles, [7][8][9][10] waste heat recovery, [11][12][13] biomedicine, [14,15] residual heat storage, [16,17] and food packaging [18,19] make them attract extensive attentions and have great research value.…”

A series of polyethylene glycol (PEG)/epoxy (EP) resin composites with various mass loadings of PEG (50%–80%), in which PEG acted as phase change materials (PCMs) and EP served as the supporting matrix to afford structural strength and avoided the leakage of melt PEG, was made via casting mold technique. The effect of PEG mass content on the form‐stability, thermal property, morphology, and mechanical property of the composite phase change materials (CPCMs) were characterized by Fourier transformation infrared spectroscope (FTIR), differential scanning calorimeter (DSC), thermogravimetric analyzer (TGA), and atomic force microscopy (AFM), respectively. The results displayed that the EP was compatible well with the PEG, and the CPCMs showed excellent form‐stability, good thermal reliability and stability even with 80 wt% PEG loading and under high temperature. In addition, the average adhesion force of the PEG/EP CPCMs increased as the PEG mass loading increased. In summary, the as‐prepared form‐stable PEG/EP CPCMs had promising potential for practical latent heat thermal energy storage (LHTES) applications.
