“…These 3D foam networks include expanded graphite, graphene aerogel, boron nitride aerogel, carbon nanotube sponge, and MXene aerogel, − whose large porous structure can prevent the migration and leakage of molten PCMs, providing a high package efficiency and high thermal conductance for the resultant phase-change composites. Therefore, a variety of phase-change composites based on organic PCMs and inorganic 3D foams have been developed for versatile applications, such as air-conditioning systems, energy-saving buildings, photothermal energy storage systems, and Li-ion batteries. − …”

Multiactuated shape memory materials are a class of promising intelligent materials that have received great interest in the fields of self-healing, anticounterfeiting, biomedical, soft robotic, and smart thermal management applications. To obtain a light/heat-dual-actuated shape memory material for thermal management applications in fire safety, we have designed a type of halogen-free flame-retardant phase-change composite film based on polyaryloxyphosphazene (PDAP)/phosphorene (PR) hybrid foam as a support material and paraffin wax (PW) as a phase-change material (PCM). PDAP was synthesized as a flexible foam matrix through the ring-opening polymerization of hexachlorocyclotriphosphazene, followed by a substitution reaction of aryloxy groups. The porosity of the PDAP foam is improved by introducing PR nanosheets, facilitating a high latent heat capacity of the PDAP−PR/PW composite films for thermal management applications. The PDAP−PR/PW composite films can implement rapid shape recovery within 65 s in the heating process, which is much shorter than that of the corresponding film without PR nanosheets (185 s). Furthermore, the PDAP−PR/PW composite films also exhibit light-actuated shape memory behavior thanks to their good solar-tothermal energy absorption and conversion contributed by PR nanosheets as a highly effective photothermal material. More importantly, the presence of PR nanosheets imparts an excellent flame-retardant property to the PDAP−PR/PW composite films. The PDAP−PR/PW composite film can be self-extinguished within 2 s after the flame. Through an innovative integration of flexible polyphosphazene foam, PR nanosheets, and solid−liquid PCM to obtain a sensitive actuating response to light and heat, this study offers a new approach for developing multiactuated and eco-friendly flame-retardant shape memory materials to meet the requirement of applications with a requirement of fire safety in soft actuators, thermal therapy, control devices, and so on.

“…Solid–liquid phase-change materials (SLPCMs) are a type of heat energy storage material that can store and release a large amount of heat energy through reversible, solid-to-liquid phase transitions [ 1 ]. SLPCMs have distinguishing features, including a high energy storage capacity, nonreactivity, and almost constant temperature during phase transitions [ 2 , 3 ].…”

Waste heat and organic contaminants are significant issues in water pollution, which has caused ecological problems and threatened human health. To provide an effective solution for wastewater recovery, we designed a novel type of multifunctional phase-change microcapsule. This type of microcapsule was synthesized using n-docosane as a core and a SiO2/Fe3O4 composite as a base shell through in situ interfacial polycondensation with the assistance of a Fe3O4 nanoparticle as a Pickering emulsion stabilizer, followed by the deposition of BiOI nanosheets on the surface of the SiO2/Fe3O4 composite shell. Benefiting from the n-docosane core, the resultant microcapsules obtained phase-change enthalpies of 46.8–115.7 J/g for absorbing waste heat from wastewater. The deposited BiOI nanosheets promoted photocatalysis for the microcapsules to degrade organic contaminants in wastewater. Owing to the magnetic response of the Fe3O4 nanoparticles, the separability and recyclability of the microcapsules were improved significantly by magnetic separation. Moreover, the microcapsules demonstrate outstanding phase-change reversibility, thermal cycling stability, and shape stability due to the tight SiO2/Fe3O4 composite shell. This study provides a promising approach for designing and developing multifunctional phase-change microcapsules for waste heat recovery and wastewater treatment.

“…Natural and biocompatible phase change materials (PCMs) are essential candidates for renewable thermal energy storage, which can help mitigate the global energy crisis associated with climate change and sustainability regulations. – PCMs can absorb and release a large amount of latent heat via simple solid-to-liquid and liquid-to-solid physical phase transitions, respectively . In recent years, organic PCMs, including long-chain alkanes (paraffin), fatty acids, fatty alcohols, and polymers, have attracted significant interest because of their high latent heat of fusion, good thermochemical stability, noncorrosivity, and nontoxicity. – Organic PCMs are generally considered a better choice than the corrosive and unstable inorganic PCMs .…”

In this study, we present an ecofriendly technique for encapsulating lauric acid (LA), a natural phase change material, within polystyrene (PS) nanofibers through coaxial electrospinning. The resulting LAPS core–sheath nanofibers exhibited a melting enthalpy of up to 136.6 J/g, representing 75.8% of the heat storage capacity of pristine LA (180.2 J/g), a value surpassing all previously reported core–sheath fibers. Scanning electron microscopy revealed uniform LAPS nanofibers free of surface LA until the core LA feed rate reached 1.3 mL/h. As the core LA feed rate increased, the fiber diameter shrank from 2.24 ± 0.31 to 0.58 ± 0.45 μm. Infrared spectra demonstrated a proportional increase in the LA content with rising core LA injection rates. Thermogravimetric analysis found the maximum core LA content in core–sheath nanofibers to be 75.0%. Differential scanning calorimetry thermograms displayed a trend line shift upon LA leakage for LA1.3PS nanofibers. LAPS fibers containing 75.0% LA effectively maintained consistent cycling stability and reusability across 100 heating–cooling cycles (20–60 °C) without heat storage deterioration. The core LA remained securely within the PS sheath after 100 cycles, and the LAPS nanofibers retained an excellent structural integrity without rupture. The energy-dense and form-stable LAPS core–sheath nanofibers have great potential for various thermal energy storage applications, such as building insulation, smart textiles, and electronic cooling systems, providing efficient temperature regulation and energy conservation.
