“…In spite of this, all the form-stable PCMs exhibited a higher thermal conductivity than that of pure paraffin. The use of recyclable skeletons such as biomass cellulose nanocrystals, [89] fly ash, [92] kapok fiber, [91] and wood fiber [90] had also improved the thermal conductivity of the formstable PCMs by more than 5% compared to the pure organic PCMs. Huang et al [89] prepared form-stable F I G U R E 9 (a) Schematic diagram of heat transfer between form-stable PCMs particles.…”

With the expansion of the global population, the energy shortage is becoming increasingly acute. Phase change materials (PCMs) are considered green and efficient mediums for thermal energy storage, but the leakage problem caused by volume instability during phase change limits their application. Encapsulating PCMs with supporting materials can effectively avoid leakage, but most supporting materials are expensive and consume huge of natural resources. Carbon materials, which are rich and renewable resources, can be used as economical and environmentally friendly supporting skeletons to prepare form‐stable PCMs. Although many researchers have begun to use recyclable materials especially various derivatives of carbon as supporting skeletons to prepare form‐stable PCMs, the preparation methods, thermophysical properties and applications of form‐stable PCMs with recyclable skeletons have rarely been systematically summarized yet. Form‐stable PCMs with a recyclable skeleton can be used as green and efficient thermal storage materials due to their high heat storage capacity and good thermophysical stability after 2000 thermal cycles. This review investigates the effects of recyclable skeletons on the thermophysical properties including phase change temperature, latent heat, thermal conductivity, supercooling, and thermal cycling reliability. Four major kinds of recyclable skeletons are focused on: biomass, biochar, industrial by‐products as well as waste incineration ash. Additionally, the application scales of form‐stable PCMs with recyclable skeletons are explicated in depth. Moreover, the main challenges confronted by form‐stable PCMs with recyclable skeletons are discussed, and future research trends are proposed. This article provides a systematic review of the form‐stable PCMs with recyclable skeletons, giving significant guidance for further reducing carbon emissions and promoting the development of sustainable energy.

Using phase change materials (PCMs) is an efficient solution for reducing energy consumption in buildings. These materials have a large capacity for storing thermal energy, making them an appealing option for energy management purposes. Phase change materials have been successfully incorporated into various construction materials such as concrete, brick, or plaster. The primary objective of this review is to examine previous studies conducted on the application of PCMs in wood. The initial section presents an overview of the direct impregnation techniques utilized for wooden materials. This is followed by a discussion on the implementation of macroencapsulated PCMs in wooden structures that are typically present in residential buildings. In addition, the use of shape-stabilized PCM/wood composites, preventing potential leaks during the phase change transition, is explored. Finally, patents related to the use of PCMs in wood are described. Future challenges include the incorporation of PCMs into wood composites to improve their thermal properties. This literature review shows that there is a gap in knowledge regarding the utilization of phase change materials in wood-based panels such as oriented strandboards, fiberboards, and particleboards. This provides an opportunity for future research to improve the performance of the products manufactured by the wood-based panels industry.

“…Experimental findings showed that the encapsulation method maximised storage capacity to 97.2 W h and rendered a highest possible energy charging speed of 109.4 W. On the other hand, Zhao et al. created a composite PCM using encapsulated Polyethylene Glycol (PEG) and Organic Diatomite (OD) with a matrix of Wood Fibre (WF) and HDPE [105] . Their results showed that the obtained FSPCM has great interface action, a high latent heat of 105.35 J g −1 and optimal packaging capability.…”

Phase Change Materials (PCMs) are utilized to regulate temperature and store thermal energy in various industries such as infrastructure, electronics, solar power, and more. However, they face several limitations, such as leakage, poor thermal properties, incompatibility, as well as high flammability. Polyethylene (PE) is one of many polymers explored to enhance the desirable properties of PCMs, due to their versatile properties such as high strength, durability, chemical resistance, and low cost. The combination of PCMs and PE can be used to create composite materials, through micro/nano-encapsulation, melt-blending, formation of composites and with proper additives. They create enhanced thermal energy storage properties and in the meantime, benefited from the mechanical properties of the PE. This review provides a concise summary of the recent developments regarding PE-enhanced PCMs and provides insights into possible topics for further investigation. We summarised enhancement methods based on commonly adopted types of PEs, such as encapsulation, melt-blending, hot pressing, extrusion, and 3D printing. We then elaborate on how these PE-PCM composites are effectively utilised for heat management applications and the potential future directions in energy-saving buildings, electronic devices, and energy storage systems.
