“…In order to improve the shape-stability of PCM, a number of from-stable PCMs have been fabricated by impregnating PCM into porous substitute, such as expanded graphite [8][9][10][11], montmorillonite [12], calcium silicate [13], diatomite [14] and wood [15,16]. Wood with hierarchical and multi-porous structure, in recent years, has been used as a porous carrier for encapsulating PCM due to the low cost, free pollution and low carbon emission [17][18][19].…”

Phase change materials attract tremendous interest for building energy conservation due to their auto-temperature regulation and thermal energy storage capacity. However, its practical application is hindered due to the leakage problem and poor photothermal conversion efficiency. To address these issues, a scalable wood-based phase change material was prepared by impregnating polyethylene glycol (PEG) into Fe3O4 doped wood particles and subsequent a hot press in this study. PEG was encapsulated by wood particles through its abundant pore structure and leakage rate of prepared wood-based phase change material (FWPCM) was only 2.9%, which solved the leakage problem effectively. FWPCM presented high latent heat of 73 J/g and slowed down the temperature change obviously. Addition of Fe3O4 powder endowed FWPCM a high photothermal conversion efficiency and thermal conductivity (0.3545 W/(m*K) was increased by 125% compared to PW. So FWPCM had potential to be used as building engineering material for energy collecting, storage and conversion benefited by its great thermal performance, superior durability, simple preparing process and acceptable mechanical property.

“…FSPCMs are one group of composites containing the porous materials as supporting materials to contain PCMs. [20] For example, the melting PCMs can be entrapped in porous materials due to capillary force during their working temperature. However, the limited thermal energy storage and phase transition of FSPCMs are found since the molecular movement of PCMs is affected by pores (e. g., pore type, pore size etc.).…”

Phase change materials (PCMs) textiles have been developed for personal thermal management (PTM) while limited loading amount of PCMs in textiles reduced thermal buffering effect. In this work, we proposed a sandwich fibrous encapsulation to store polyethylene glycol (PEG) with PEG loading amount of 45 wt %, which consisted of polyester (PET) fabrics with hydrophobic coating as protection layers, polyurethane (PU) nanofibrous membranes as barrier layers and PEG‐loaded viscose fabric as a PCM‐loaded layer. The leakage was totally avoided by controlling weak interfacial adhesion between protection layer and melting PEG. The sandwich fibrous PEG encapsulations had an overall melting enthalpy value ranging from 50 J/g to 78 J/g and melting points ranging from 20 °C to 63 °C by using different PEGs. Besides, introduction of Fe microparticles in PCM‐loaded layer enhanced thermal energy storage efficiency. We believe that the sandwich fibrous PEG encapsulation has a great potential in various fields.

“…5 In addition, the use of agricultural residues and plastic waste is more sustainable, and their recycling properties make them an environmentally friendly product. [6][7][8] As natural plant fibers are hydrophilic and have strong chemical polarity, the interface compatibility with non-polar thermoplastics is poor, which limits the further improvement and applicability of WPCs. 9,10 Chemical treatment, physical treatment, and hybrid inorganic nanoparticles are commonly used to improve the interfacial bonding strength between wood fiber and plastic matrix.…”

The effects of ultrasonic and hydrothermal treatment on the physical, mechanical, wear resistance, water absorption and thermal stability of the walnut shell (WS)/attapulgite (ATP)/polyvinyl chloride (PVC) composite and its enhancement mechanism were investigated. WS was treated by ultrasound and hydrothermal treatment and mixed with PVC and ATP, and the WS/ATP/PVC composites were prepared by melt extrusion. The properties of composites were characterized, and the results showed that after ultrasonic and hydrothermal treatment, the main chemical structure of composites was not changed significantly. Compared with untreated composites, the wear resistance after ultrasonic treatment for 10 min is the best. After ultrasonic treatment for 15 min, the bending strength, tensile strength and impact strength of the composite are increased by 8.9%, 10.3% and 46.2%, respectively. Hydrothermal treatment at appropriate temperatures also improved some properties of the composites. The composites after hydrothermal treatment at 110°C had the best thermal stability and highest hardness, and the bending strength and tensile strength values were increased by 5.9% and 5.2%, respectively. The impact strength of the composite increased with the increase of hydrothermal treatment temperature. The results showed that ultrasonic and hydrothermal treatments have the potential to improve the performance of wood–plastic composites as environmentally friendly pretreatment methods.
