“…[6] In addition, as the core working substances, PCMs are promising for its potentials in both cooling and heating with its capability to store and release thermal energy with constant temperature. [7] Therefore, PCMs have attracted most attention and been used in various practical occasions such as water heating, [8] data center cooling, [9] building comfort, [10] thermal management, [11] energy storage.

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.

Inorganic SiO 2 microencapsulated phase change materials (MEPCMs) have been developed via polymerization reaction and electrostatic interaction in an emulsion system. The resultant microcapsules were systematically characterized in terms of morphology, composition, thermal stability, durability and mechanical property. The energy storage capacity of the obtained microcapsules ranges from 190.5 J/g to 225.5 J/g (pure octadecane: 250.6 J/g) when the core material is octadecane at different sizes. SiO 2 -PCM microcapsules showed improved energy storage efficiency in terms of shorter melting and freezing durations attributed by the higher thermal conductivity of inorganic silica shell compared with that of polymer shell encapsulated PCM. Repeatable melting and freezing processes after 150 cycles revealed excellent shell tightness and thermal stability of the resultant microcapsules. The high apparent compressive strength of individual SiO 2 -PCM microcapsule indicated good survivability in further materials processing for energy storage. The robust SiO 2 -PCM microcapsules obtained from a facile fabrication approach in this study have great potential applications for developing energy efficient materials.

“…Shape stability of PCMs is a very important technological problem. Certain carbon nanomaterials and expanded graphite can improve shape stability of PCMs significantly [22] but also allow their scale up to real applications [23]. The use of PCMs in laminated composite structures has also made some advances recently [24].…”

Leaching and instability in wax-based phase change materials (PCMs) are serious application problems. Herein, we developed paper-like (~ 100 µm) flexible, composite PCMs by hydraulic compression of 1-cm-thick polyimide foams between an aluminum foil and a (nano) ceramic composite Parafilm®. An unfilled PCM film placed between the foam and the aluminum surface ensured strong adhesion between the collapsed foam and the metal. Different concentrations of nano-BN and micro-SiC particles were compounded into Parafilm® in order to optimize the thermal performance. Based on infrared imaging, the monoliths containing 30 wt% micro-SiC outperformed all other systems including BN/SiC hybrids. The next best thermal performance was observed with the 60 wt% nano-BN composite. Due to compression, the cellular structure of the polyimide foams collapsed irreversibly while being impregnated by the PCMs from both sides. High-k fillers improved impregnation into the collapsed foam and enabled excellent shape stability and leakage prevention. Graphical abstract
