“…As an energy management material, the PCM can effectively compensate for the time and space difference in the process of energy use, which is now widely used in buildings, solar energy, and industrial waste heat collection. 187,188 Heat storage and release in PCMs are dependent on phase change. PCMs can store the heat released during hydrogen absorption and supply it to the MHB during hydrogen desorption in the MHR, which reduces the use of external heat sources, improves the efficiency of energy utilization, and enhances the heat transfer effect of the MHB.…”

“…Among the various TES technologies, latent heat storage technologies are widely studied for their simplicity of operation and high energy storage density at almost constant temperatures based on phase change materials (PCMs). − In fact, PCMs store and supply thermal energy by absorbing and releasing latent heat during phase change. In multitudinous PCMs, poly(ethylene glycol) (PEG) has been widely studied by virtue of its high latent heat, suitable phase change temperature, many reactive reagents, good thermal stability, and nontoxicity. − Regretfully, PEG still requires special encapsulation techniques to prevent its fluidity and leakage during the solid–liquid phase change, which limits its practical application. − To solve this key issue, PEG can often be covalently combined to form chemically cross-linked structures with other chemicals, resulting in solid–solid PCMs (SSPCMs) containing PEG. , …”

Phase change materials (PCMs) with energy-saving and sustainable energy potential are widely available for energy storage technologies. At present, chemical cross-linking is often constructed to form solid–solid phase change materials (SSPCMs) to avoid leakage during the phase change process, but its permanent cross-linked network cannot be reprocessed, resulting in nonrecyclable materials with very high environmental impact. Herein, we prepare a series of poly(ethylene glycol) (PEG)-containing reprocessed solid–solid phase change materials (RSSPCMs) based on dynamic disulfide bonds, which were in the solid state even at high temperatures. These RSSPCMs had high latent heat with a maximum value of 100.2 J/g, which exhibited remarkable thermal storage capacity in addition to excellent solar-thermal conversion capacity. Interestingly, the introduction of dynamic disulfide bonds in the molecular structure provided RSSPCMs with excellent self-healing properties and recyclability. Broken RSSPCM samples could heal under thermal-induced and infrared radiation-induced reprocessing. Importantly, the chemical structure, crystallization behavior, and phase transition ability of RSSPCMs could also remain unchanged after multiple recycling. Designing RSSPCMs based on dynamic disulfide bonds is important for achieving the efficient utilization of solar energy and environmental protection.

“…Unfortunately, when the solid–liquid PCMs was employed in practical applications, several inferiors including low thermal conductivity, easy leakage, and volume change, can hinder the prosperity of TES system in various application scenarios. To address aforementioned bottlenecks, enormous efforts have been devoted to constructing shape-stabilized PCMs [ 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. In particular, microencapsulated phase change materials (MEPCMs) using PCMs as capsule cores and a polymer or inorganic materials as shells have been extensively investigated, which was expected to prevent the leakage and erosion of melting PCMs during phase change process.…”

Phase change materials (PCMs) have been extensively utilized in latent thermal energy storage (TES) and thermal management systems to bridge the gap between thermal energy supply and demand in time and space, which have received unprecedented attention in the past few years. To effectively address the undesirable inherent defects of pristine PCMs such as leakage, low thermal conductivity, supercooling, and corrosion, enormous efforts have been dedicated to developing various advanced microencapsulated PCMs (MEPCMs). In particular, the low-dimensional thermally conductive nanofillers with tailorable properties promise numerous opportunities for the preparation of high-performance MEPCMs. In this review, recent advances in this field are systematically summarized to deliver the readers a comprehensive understanding of the significant influence of low-dimensional nanofillers on the properties of various MEPCMs and thus provide meaningful enlightenment for the rational design and multifunction of advanced MEPCMs. The composition and preparation strategies of MEPCMs as well as their thermal management applications are also discussed. Finally, the future perspectives and challenges of low-dimensional thermally conductive nanofillers for constructing high performance MEPCMs are outlined.
