“…In Chen's work, [35] graphene sponge was adopted to absorb two kinds of fatty amine to fabricate SSPCMs, resulting from super low density of graphene sponge, the SSPCM achieved a loading rate as high as 7063-10660 wt.% compared to fatty amine. Additionally, both of the SSPCMs show high energy storage and low supercooling which ranges from 7-9 ℃, the materials could be a good candidate for energy storage.…”

“…However, the thermal enthalpy decreased due to the less impregnation ratio of PCMs in the composites. To simultaneously prove thermal conductivity and impregnation ratio, [35] EG was introduced as a support matrix together with diatomite at a weight ratio of 1:10 (EG to diatomite), devised LA-SA/ diatomite /EG SSPCM with 72.2% loading rate of LA-SA acquired a phase change temperature of 31.17 ℃, the material also showed latent heat value of 117.30 J g -1 for melting and 114.50 J g -1 for freezing. The thermal conductivity of LA-SA/ diatomite /EG was up to 3.2 times that of LA-SA/ diatomite.…”

Organic phase change materials (OPCMs) are advanced energy storage materials with ability to storage and release thermal energy at constant temperature. Efficient energy storage systems using shape-stabilized PCMs (SSPCMs) are promising to adjust the gap between energy supply and demand. The performances of SSPCMs are influenced by multiple factors which are necessary to be considered in the fabrication process. In this regard, we summarized the desired properties for OPCMs and SSPCMs, then we systematically discussed the fabrication methods involving supporting materials, OPCMs and fillers. At last, we elaborated thermal storage applications of SSPCMs from three kinds of energy sources. This review intends to provide in-depth and constructive insights into the fabrication and energy storage applications of SSPCMs, thereby contributing to development and application of high-performance SSPCMs.

“…8,9 Since porous materials can provide load space for PCM, many novel porous carriers have been reported recently, such as three-dimensional (3D) porous TiO 2 , 10 copper foam, 11 3D graphene sponge. 12,13 Nevertheless, these carrier materials are expensive and complicated to prepare. 14,15 Clay mineral materials have low cost, comprehensive sources, and good compatibility with organic PCM.…”

Expanded dickite as the carrier of loading polyethylene glycol (PEG), a novel composite phase change material (PCM) is synthetized. X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, specific surface area test, thermogravimetric analysis, and differential scanning calorimetry are used to characterize and evaluate the expanded dickite carrier and the composite PCMs. The results show that the heat released by the reaction of potassium chlorate and urea promotes the layer expansion of dickite to form a net-like porous structure. Two kinds of expanded dickite (EDU1 and EDU2) carriers are prepared by modulating the amount of potassium chlorate. EDU2 carrier with full layer expansion possesses a PEG load rate of 179.3%. The higher PEG load rate of EDU2 is attributed to its developed pore structure, and the hydrogen bond formed between PEG and expanded dickite. Composite PCM using EDU2 as the carrier has a higher latent heat of 98.22 J g À1 and good thermal cycling stability.

Form-stable phase-change materials (FSPCMs) are of great significance for relieving the contradiction of energy supply and demand. Unfortunately, the practical application of FSPCMs is severely compromised by their intrinsic drawbacks including lower latent heat storage (LHS) capacities, inferior interfacial compatibility, and cycling durability. Herein, we have provided a group of novel FSPCMs with higher LHS capacities, using paraffin as the LHS materials, which tightly intertwines with the 1-octadecylamine-modified montmorillonite (C18-MMT) under the capillary action as well as induced dipole force due to its n-alkyl chains compatibility. The obtained composite FSPCMs not only exhibit high melting enthalpies (137.56 J/g) but also demonstrate enhanced shape stability and thermal stability. In addition, the composites also render an impressive long-term thermal cycling capability and structure stability even after 100 thermal cycling durability tests, which are believed to have great potential for application in the thermal management of green energysaving buildings.
