“…Carbon fibre was selected by Zou et al 104 to support Al matrix composite with a self‐encapsulated silicon structure through rotating magnetic field. Various weight percentages of Si were utilized to prepare Al‐Si alloy, and it was obtained the thermal conductivity improvement of shell from 65.2 to 100.7 W/m K as the increase of the Si content in initial Al‐Si from 25 to 40 wt% of Si.…”

Summary Microencapsulated phase change materials (MEPCMs) have made tremendous advancements in recent years, owing to their increased demand for a variety of energy storage applications. In this paper, current microencapsulation techniques, enhancement, and use of medium‐ and high‐melting phase change materials (PCMs) are reviewed, as well as their potential benefits and limitations. The most frequently employed PCMs for medium‐ and high‐temperature applications were recognized as salt‐based, metallic, inorganic compound, and eutectic. Meanwhile, polymethyl methacrylate (PMMA), polystyrene‐butylacrylate (PSBA), polyethyl‐2‐cyanoacrylate (PECA), and polyurethane were widely used as polymer shell materials for encapsulating medium‐ and high‐melting point PCMs via chemical method, whereas inorganic silica shell was synthesized via various techniques. Hydrolysis followed by heat‐oxidation treatment has been extensively studied since 2015 to encapsulate either metal or alloy within Al2O3 shells. Different techniques were developed to generate void between core and shell material to accommodate volume expansion during phase transition. Numerous approaches, including the incorporation of metal particles, carbon, and ceramic, have been found as ways to enhance the thermal performance of PCMs. Multiple storage arrangements were also established to be an effective way of enhancing the overall efficiency of medium‐high melting PCM storage systems. Finally, the paper highlights the potential of medium‐ and high‐melting temperature PCMs for solar power generation, solar cooking, and industrial waste heat recovering applications.

“…To improve the thermal conductivity of PCM, carbon‐based and metal‐based materials have been used as enhanced additives 13 . Carbon‐based materials include expanded graphite, 14,15 carbon fibers, 16,17 carbon black, 18 carbon nanotubes, 19 and graphene 20,21 . For example, Mishra et al 22 prepared lauric acid‐based phase change material loaded with carbon black nanoparticles, and demonstrated that the carbon black nanoparticles could greatly improve the thermal conductivity.…”

Recently, the technology of employing phase change materials (PCMs) for solar energy storage has grown more magnetic due to the focus of various latent heat storage investigations to solve the energy crisis. In this work, a novel and ecofriendly shape-stable phase change material based on a biological matrix was prepared through vacuum impregnation, which used porous carbon as a support substrate from Cyperus alternifolius (CA), polyethylene glycol (PEG) as the phase change medium, and silver nanoparticles attached to the matrix as the reinforcement factor. The superior porous structure of CA allows it to have a high loading rate of PEG. The multifunctionality of silver nanoparticles can increase the thermal conductivity of the bio-based shape-stable phase change material (BSPCM) up to 0.676 W/(m K), while also boosting its photo-thermal conversion efficiency to 82.7%. Furthermore, the Ag@BSPCM has an excellent melting enthalpy of 137.3 J/g, as well as outstanding thermal stability and reliability. Additionally, the great photo-to-thermal conversion efficiency of Ag@BSPCM (82.7%) and the significant anti-leakage capability bodes well for its future application. This demonstrates the prepared Ag@BSPCM proves its feasibility for thermal energy storage management and photo-thermal conversion.
