“…In another study, a magnetic wood-based composite PCM was fabricated using delignified balsa wood as a base material due to its structural stability during phase-change progression. [225] In this work, different weight percentages (1%, 2%, 5%, and 8%) of magnetic Fe 3 O 4 nanoparticles (>99.5%, average particle size of 20 nm) were mixed with melted tetradecanol (TD, ≥99%). The DW was then vacuum impregnated with TD and Figure 23c shows photomicrographs of the prepared samples and demonstrates the shape stability at lower and higher temperatures.…”

performance environmentally friendly materials. This is because new processes will be required that allow control on all hierarchical levels. Wood is well defined as a biological engineering material with a complex hierarchical structure of organic material based on cellulose fibrils embedded in a matrix of hemicelluloses and lignin. [1,2] Wood has long been used as a construction material, as well as for pulp and paper production. These applications are highly dependent on the properties of lignin in wood. Removal of lignin is the key step in pulp and paper production, in addition to the conversion of biomass to liquid biofuels. Lignin was first discovered in wood by Anselme Payen in 1839, [3] as the incrusting material that must be removed to isolate the useful fibers in wood. Research pertaining to wood nanotechnology or functional wood materials is a rapidly emerging field. Functional wood materials are mostly fabricated by treating hierarchical natural templates (wood cell wall) by chemical and thermal means. These treatments selectively modify the wood cell wall structure (fine pore spaces and inner lumen surface area) for different applications. [4] The pore region and inner lumen surface have actively been modified to enhance the bulk properties of wood using organic chemicals, [5] inorganic chemicals, organic-inorganic chemicals, [6,7] and thermal methods. [8] Hybrid wood scaffolds have been prepared for diverse applications such as magnetic wood, [9,10] as well as wood-mineral and wood-metal hybrids. [11] Recent research on delignified wood (DW) has emerged from the classical pulp production method. In the preparation of DW, the embedded lignin is removed from the wood cell wall structure, while maintaining the natural hierarchical cellulosic structure. [12] Initially, DW was prepared in order to understand the unknown ultrastructure of wood cell walls. However, since 2015, research in this area has rapidly expanded to focus on the development of wood-based functional scaffolds. Within the literature, DW is predominantly prepared using alkaline delignification methods such as Kraft pulping (a mixture of sodium hydroxide (NaOH) and sodium sulfite (Na 2 SO 3 )) heated to boiling temperature), followed by bleaching using hydrogen peroxide (H 2 O 2 ) to remove the lignin. DW is chemically hydrophilic due to the presence and exposure of hydroxyl groups and possible sites for DW functionalization. DW scaffolds have been functionalized

“…Moreover, the composite PCMs also integrate high thermal energy storage of 100 J/g, outstanding thermal stability, and reversibility. Similarly, Yang et al 86 introduced Fe 3 O 4 NPs into delignified balsa wood to fabricate magnetic Review wood-based composite PCMs for magnetic-to-thermal and solar-to-thermal conversion. Benefiting from the magnetothermal effect of Fe 3 O 4 NPs, the magnetic wood-based composite PCMs can be heated under an alternating magnetic field.…”

Efficient thermal energy storage technologies based on phase change materials (PCMs) that are capable of reversibly harvesting tremendous thermal energy during the isothermal phase transition have recently received unprecedented attention and are booming explosively in the exploitation of state-of-the-art multifunctional composite PCMs. In this regard, the smart integration of versatile metal oxides into PCMs has made significant contributions. However, a comprehensive review associated with the smart utilization of multifunctional metal oxides in PCMs is lacking. Here, we systematically summarize recent advances concerning the smart utilization of multifunctional metal oxides in PCMs for thermal storage, thermal transfer, energy conversion, and advanced versatile applications. This review aims to provide in-depth insights into the interactive relationships between multifunctional metal oxides and PCMs, thus providing a guide for the target design of high-performance multifunctional composite PCMs. We also highlight the current challenges and possible future research directions.

Form-stable phase-change materials (FSPCMs) are of great significance for relieving the contradiction of energy supply and demand. Unfortunately, the practical application of FSPCMs is severely compromised by their intrinsic drawbacks including lower latent heat storage (LHS) capacities, inferior interfacial compatibility, and cycling durability. Herein, we have provided a group of novel FSPCMs with higher LHS capacities, using paraffin as the LHS materials, which tightly intertwines with the 1-octadecylamine-modified montmorillonite (C18-MMT) under the capillary action as well as induced dipole force due to its n-alkyl chains compatibility. The obtained composite FSPCMs not only exhibit high melting enthalpies (137.56 J/g) but also demonstrate enhanced shape stability and thermal stability. In addition, the composites also render an impressive long-term thermal cycling capability and structure stability even after 100 thermal cycling durability tests, which are believed to have great potential for application in the thermal management of green energysaving buildings.
