“…Generally speaking, sol-gel method is mainly used for organic PCMs encapsulation. However, Milian and Ushak [216] empowered this method to encapsulate inorganic PCMs but using ethanol and only TEOS as precursor. During this study, they employed different monomer and solvent.…”

“…Similarly, Fang et al [50b] microencapsulated Na 2 HPO 4 • 7H 2 O, which due to the PCM being confined within the silica shell, led to a 15 % reduction in supercooling. Other encapsulation of inorganic salts, such as by sol-gel encapsulation of LiNO 3, [64] melt blending of Zn(NO 3 ) 2 • 6H 2 O into EP, [42a] or vacuum impregnating NaNO 3 into EV, [41] the encapsulating matrix was effective in reducing supercooling by 24 %, 30 % and 42 % respectively. Sol-gel encapsulation of PEG was also effective in reducing supercooling, [73] where Tang et al [67a] tested with four different molecular weight PEG 1000, 2000, 4000 and 6000, and all except PEG 2000 recorded a reduction in supercooling by 26 %, 13 % and 36 % respectively.…”

In fact a work by Milian et al [64] showed that using appropriate solvents that better dissolve the PCM for sol-gel reactions help to homoge-nously distribute the PCM across the SiO 2 matrix and reduce supercooling.…”

“…Inorganic PCMs are less commonly incorporated partly due to poorer compatibility, and they present issue of supercooling and phase separation. Nevertheless, Milian et al [64] fabricated a series of form-stable PCMs involving LiNO 3 as PCM via sol-gel, and studied the effects of using different silicon precursors on the phase change performance. The different silicon precursors used include TEOS, (3-glycidyloxypropyl) trimethoxysilane (GPTMOS), trimethoxy [3-(methyl-amino)propyl] silane (APT-MOS) and trimethoxy (2-phenylethyl) silane (PhTMOS).…”

Phase change materials (PCMs) have been widely recognized as efficient solutions for thermal management across various industries, including logistics, construction, electronics, and others. Nevertheless, these materials encounter challenges such as leakage, poor thermal conductivity, and supercooling. To address these challenges, a comprehensive examination was conducted on the recent advancements pertaining to silicon‐based materials. These studies include their application as high temperature PCMs, as encapsulation matrices, and their integration as additives to enhance material properties. Aluminum–silicon (Al−Si) alloys offer a viable thermal management solution for high‐temperature applications, such as those found in car batteries. Silicon dioxide (SiO2), silicon carbide (SiC), and silicate‐based minerals have demonstrated the ability to synergistically encapsulate PCMs to prevent leakage, enhance thermal conductivity, and mitigate supercooling. However, the efficacy of these strategies in reducing supercooling varies, and a considerable number of studies have reported an exacerbation. Therefore, appropriate material selection and fine tuning for formulation are necessary. This review critically assesses silicon‐based materials as a component of PCM composite that have been developed over the years. Also, it presents an academic analysis of the selection of silicon‐based materials and the design strategy for PCM composites to optimize PCM formulations according to specific desired properties.

The energy consumption for cooling takes up 50% of all the consumed final energy in Europe, which still highly depends on the utilization of fossil fuels. Thus, it is required to propose and develop new technologies for cooling driven by renewable energy. Also, thermal energy storage is an emerging technology to relocate intermittent low-grade heat source, like solar thermal energy and industrial waste heat as well as to exploit off-peak electricity, for cooling applications. This review aims to summarize the recent advances in thermally driven cooling and cold storage technologies, focusing on the formation and fabrication of adopted composites materials, including sorption materials, phase change materials, and slurries. Herein, first the classifications, selection criteria, and properties for these three types of materials is discussed. Then, the application potentials of all the materials are prospected in terms of economic analysis and sustainability.
