“…Solar-thermal materials are capable of harnessing solar energy, which has been widely used in power generation, thermal energy storage, water purification, and sterilization systems over the past decades. , An ideal solar-thermal material should effectively absorb solar irradiation over the entire solar spectrum with high solar-thermal conversion efficiency. The solar-thermal effect produced by solar excitation exists in diverse kinds of nanostructured materials, such as carbon materials, metallic materials, semiconductors, and some conjugated polymers, etc. − Upon solar irradiation, these solar-thermal materials convert solar energy into thermal energy through different solar-thermal conversion mechanisms, which are related to their inherent electronic or bandgap structures. Generally, solar-thermal conversion mechanisms can be categorized into three categories, namely conjugate effect and hyperconjugate effect, surface plasmon resonance (SPR) effect, and localized SPR (LSPR) effect, and nonradiative relaxation effect. − …”

Functional phase change materials (PCMs) capable of reversibly storing and releasing tremendous thermal energy during the isothermal phase change process have recently received tremendous attention in interdisciplinary applications. The smart integration of PCMs with functional supporting materials enables multiple cutting-edge interdisciplinary applications, including optical, electrical, magnetic, acoustic, medical, mechanical, and catalytic disciplines etc. Herein, we systematically discuss thermal storage mechanism, thermal transfer mechanism, and energy conversion mechanism, and summarize the state-of-the-art advances in interdisciplinary applications of PCMs. In particular, the applications of PCMs in acoustic, mechanical, and catalytic disciplines are still in their infancy. Simultaneously, in-depth insights into the correlations between microscopic structures and thermophysical properties of composite PCMs are revealed. Finally, current challenges and future prospects are also highlighted according to the up-to-date interdisciplinary applications of PCMs. This review aims to arouse broad research interest in the interdisciplinary community and provide constructive references for exploring next generation advanced multifunctional PCMs for interdisciplinary applications, thereby facilitating their major breakthroughs in both fundamental researches and commercial applications.

“…Significantly, the transform temperature and heat content could be controlled by adjusting the molecular mass and the PEG amount. Recently, Lang et al 33 prepared a set of solid–solid phase‐change membranes generated from cellulose with thermo‐reversible optical characteristics by introducing and stabilizing phase change molecules utilizing building of a cross‐linking network. The membranes exhibited excellent thermo‐reversible optical transparency, increasing from around 5% to over 90% as temperature increased and becoming untransparent immediately after return to room temperature.…”

Phase‐change material (PCM) has great thermal energy ability, which has been used as building material for energy conservation. While the most widely used solid–liquid PCM usually appeared leakage during the phase change transition. In order to overcome the leakage of solid–liquid PCM and prepare a viable building energy‐saving materials for indoor temperature regulation, thermal energy storage composites were prepared by utilizing cellulose grafted PEG as phase change material (PCM) and high‐density polyethylene (HDPE) as the substrate. The liquid leakage of PEG was solved after graft to fabricate solid–solid PCM. HDPE is beneficial for solving the leakage and improving the mechanical property by its secondary encapsulation. The synthesized Cellulose‐PEG was characterized by scanning electron microscopy (SEM), X‐ray diffractometer (XRD), and differential scanning calorimetry (DSC). Thermal and mechanical characteristics of the composite were explored. The outcomes revealed that: (1) PEG was successfully grafted to the surface of cellulose and Cellulose‐PEG showed solid–solid phase change behavior. (2) Both the melting‐cooling temperatures and the thermal stability of solid–solid wood plastic composite (SSWPC) had the potential as thermal energy storage material for temperature regulating. (3) The addition of Cellulose‐PEG adversely affected moisture resistance, flexural property, and impact strength due to the weak interface bonding. The physical and mechanical degradation was tolerable for applying situation where mechanical performance is less crucial.Highlights Cellulose‐PEG showed solid–solid phase change behavior without liquid leakage. High‐density polyethylene (HDPE) was used as the matrix to realize the second encapsulation of PCM. Cellulose‐PEG negatively influenced the physical and mechanical property of HDPE. Solid–solid wood plastic composite presented great thermal storage capacity for indoor temperature regulating.

“…One of the greatest challenges for a future sustainable society is the use of renewable and environmentally friendly material resources that can replace fossil-based products to produce high-performance functional materials. Therefore, in recent decades more and more attention has been given to the utilization of bio-based polymers such as cellulose, which offers many advantages, for instance, being renewable, biodegradable, and recyclable [1][2][3][4][5][6]. Some of the most interesting cellulose-based materials are cellulose nanofibrils (CNFs) which exhibit numerous intrinsic advantages, including high elastic modulus, remarkable strength, high specific surface area, and high aspect ratio, which make them promising for a variety of applications ranging from drug delivery and water purification to composites [7][8][9][10].…”

This paper presents a strategy to convert hydrophilic cellulose nanofibrils (CNF) into a highly cross-linked hydrophobic network with inorganic nanoparticles to develop a gel ink suitable for gel 3D printing. The CNF were chemically modified initially through a single-electron transfer-living radical polymerization (SET-LRP) of stearyl acrylate (SA) in the presence of the surface-modified cobalt iron oxide (CoFe2O4, CFO) nanoparticles. The modified CFO nanoparticles provide their multifunctional properties, such as magnetic and electrochemical, to the CNF hybrid network and, at the same time, act as cross-linking agents between the nanocellulose fibrils, while the grafted poly-stearyl acrylate (PSA) introduces a strong hydrophobicity in the network. A suitable gel ink form of this CNF–PSA–CFO material for gel 3D printing was achieved together with a certain solvent. Some test structure prints were directly obtained with the CNF–PSA–CFO gel and were used to evaluate the consolidation of such 3D objects through solvent exchange and freeze-drying while also keeping the magnetic and electrochemical properties of CFO in the CNF-based composite intact. The pristine CNF and CFO particles and the CNF–PSA–CFO were characterized by FTIR, SEM, XPS, TGA, VSM, and CV measurements.
