Multifunctional and long-term stable wearable heating systems have attracted extensive attention from experts, yet smart textiles that only rely on harvesting the body’s heat without additional energy still face huge challenges in practical applications. Herein, we rationally prepared the monolayer MXene Ti3C2Tx nanosheets via an in situ hydrofluoric acid generation method, which was further employed to construct a wearable heating system of MXene @ polyester polyurethane blend fabrics (MP textile) for the passive personal thermal management through a simple spraying process. Owing to the unique two-dimensional (2D) structure, the MP textile presents the desired mid-infrared emissivity, which could efficiently suppress the thermal radiation loss from the human body. Notably, the MP textile with an MXene concentration of 28 mg/mL exhibits a low mid-infrared emissivity of 19.53% at 7–14 μm. Significantly, these prepared MP textiles demonstrate an enhanced temperature of more than 6.83 °C compared with those of favorably traditional fabrics, involving the black polyester fabric, pristine polyester polyurethane blend fabric (PU/PET), and cotton, suggesting a charming indoor passive radiative heating performance. The temperature of real human skin covered by MP textile is 2.68 °C higher than that covered by cotton fabric. Impressively, these prepared MP textiles simultaneously possess attractive breathability, moisture permeability, mechanical strength, and washability, which provide new insight into human body temperature regulation and physical health.

MXene-based infrared camouflage materials have garnered significant interest due to their intrinsic low emissivity. However, their practical application in marine environments is largely hindered by MXene’s susceptibility to oxidation. To overcome this limitation, we propose a protective strategy involving poly(tannic acid) (PTA), which is grafted onto MXene via hydrogen bonding and coordination interactions. This PTA layer acts as a barrier against H 2 O and O 2 ingress while enhancing the interfacial adhesion between adjacent MXene nanosheets, thereby improving the structural integrity of the composite film. Density functional theory (DFT) calculations reveal a strong affinity between PTA and MXene, confirming that both chemical interactions and physical barrier mechanisms contribute to the significantly improved oxidation resistance. Importantly, the functionalized MXene/PTA composite retains the low infrared emissivity inherent to pristine MXene. After 3 days in a simulated marine environment, the MP-5 (5 wt% PTA-modified MXene) film showed only a slight increase in emissivity, from 0.15 to 0.17. Even after 20 days of exposure to high temperature and humidity, the composite maintained a low emissivity of 0.22, demonstrating exceptional durability in thermal camouflage performance. This work offers a feasible and effective approach for designing environmentally stable MXene-based materials suitable for long-term infrared camouflage in marine settings.

Radiative cooling (RC) technology has attracted significant attention for enabling passive heat dissipation without energy consumption. However, the low thermal conductivity of polymer-based materials poses significant challenges to their practical application in devices with internal heat sources. To address this issue, we developed a dual-functional composite film by embedding a three-dimensional porous copper foam skeleton into a TiO 2 /SiO 2 -filled polydimethylsiloxane (PDMS) matrix. The as-fabricated composite film exhibits a high thermal conductivity of up to ∼ 6.70 W m −1 K −1 while maintaining a high average emissivity( ε ¯ 8-13μm ) of ∼ 0.91 within the atmospheric window (8‒13 µm). Simulated heat dissipation testing revealed that, under nocturnal simulated heat source conditions, the 60 PPI composite film achieved a temperature reduction of approximately 4.16 °C compared to traditional radiative cooling materials. This synergistic design overcomes the critical thermal bottleneck of conventional RC materials, providing a promising pathway for the passive thermal management of high-power-density electronic devices.

Traditional infrared stealth technology focuses on fixed infrared stealth materials that reduce surface infrared emissivity and heat insulation, making it difficult to meet the needs of complex environments. Conventional stealth materials do not work well for equipment that is prone to high temperatures, so the development of intelligent infrared stealth materials with excellent thermal insulation properties has broad application prospects. Here, we first prepared an aerogel material with shape memory effect and tunable emissivity by selecting polyethylene glycol diacrylate (PEGDA), chitosan (CS), and vanadium dioxide (VO2). The resulting aerogel has a low heat distortion temperature (about 70 °C) and excellent mechanical properties (more than 85% stress effect even after 100 compression cycles), significant deformation effect (morphology change rate of about 28%), and emissivity transition characteristics (from 0.921 to 0.596). Importantly, as the aerogel is heated back to its original fluffy structure, it enhances its thermal insulation effect and the emissivity of the VO2 coating gradually decreases. As expected, after reaching thermal equilibrium at 100 °C, the aerogel not only recovers its original structure but also maintains its surface temperature at about 40 °C, and its adaptive surface IR emissivity decreases to provide a proper IR stealth effect.

Passive daytime radiative cooling (PDRC) has been considered an effective zero-power cooling method, and colored PDRC films can efficiently avoid glare effects as well as expand aesthetic and functional demands. However, the spectral designs of most colored radiative coolers are complex, and they have shortcomings in adaptability to weather changes due to static optical properties. It remains a great challenge to develop self-adaptive colored radiative coolers for all-humidity efficient radiative cooling and to expand moisture-responsive applications. Herein, based on the bionic concept derived from the color-changing characteristic of chameleons in response to environmental conditions, an insight into humidity-driven dynamically reversible dual-band spectral regulation is proposed. Humidity-sensitive colored film (HSCF) possessing spectral self-regulation abilities across both solar and mid-infrared wavelength ranges is developed, which shows dynamically enhanced solar reflection and mid-infrared emissivity as ambient humidity increases. Outdoor tests demonstrate that the obtained colored film can achieve self-adaptive efficient PDRC over a wide ambient humidity range (25–90%) throughout the whole day. More importantly, the dynamic dual-band regulation process is autonomous, energy-free, and reversible. This work provides a route to develop self-adaptive colored radiative coolers for application in all humidity conditions.

High infrared emissivity coatings have important engineering value in aerospace and electronic devices. In this study, a new method for preparing high infrared emissivity coatings using magnetic field-assisted jet electrodeposition was prepared. The magnetic field-assisted jet electrodeposition technique can be used to prepare coatings with rough structures, and the infrared emissivity of nickel particle coatings can reach 0.80 at a magnetic field intensity of 100 mT, which is significantly improved compared with the nickel coatings (0.155) prepared by conventional electrodeposition. A nickel-based SiC composite coating with high infrared emissivity was prepared by combining magnetic field-assisted jet electrodeposition with SiC particles. Compared with the nickel particle coating, the infrared emissivity of the nickel-based SiC composite coating is further improved. At a concentration of 6 g/L SiC particles, the infrared emissivity of the nickel-based SiC composite coating reached 0.94. The synergistic effect of magnetic field-assisted jet electrodeposition and SiC particles can realize the nickel coatings into coatings with high infrared emissivity.

Semiconductor oxides are ideal candidates for future electromagnetic wave absorption and thermal management due to their hole-conducting properties. However, in practical applications, due to its limited conductivity, its development and application in the field of electromagnetic wave absorption and thermal management are greatly limited. The CuAl 1-x Fe x O 2 ceramics were synthesized using the high-temperature solid-phase method to study their microwave absorption and infrared emissivity characteristics. The introduction of Fe significantly improves the electromagnetic wave absorption and emissivity characteristics of CuAlO 2 ceramics. The effects of Fe doping on the dielectric constant, permeability, microstructure, and surface morphology of the composite were systematically analyzed. The results show that Fe doping leads to lattice distortion and the introduction of defects, which effectively improves the conductivity and polarization loss of the material, thus enhancing the dielectric loss and magnetic loss mechanisms of the material and obtaining excellent microwave absorption performance. The results show that when the doping amount of Fe is 3 %, the minimum reflection loss RLmin can reach −50.41 dB, and the effective absorption bandwidth EAB is 4.2 GHz. When the doping amount of Fe is 9 %, the infrared emissivity reaches a peak of 0.936. The porous structure further enhances the absorption and radiation properties of CuAl 1-x Fe x O 2 ceramics. It is further indicated that CuAl 1-x Fe x O 2 ceramics have great application potential in electromagnetic wave absorption and thermal management.

High-purity, nano-sized (Ti 0.2 Zr 0.2 Nb 0.2 Mo 0.2 Hf 0.2 )B 2 (TZNMH) diboride powders were successfully synthesized via a combined flocculation precipitation and boro/carbothermal reduction method. Then, the solid solution formation, thermal radiation performance and mechanical properties of TZNMH were investigated. It is found that high entropy effect endows TZNMH ceramic with outstanding near-blackbody radiation performance in the UV-Vis-NIR region, with a thermal emissivity ≥ 95%. This is because high entropy induces robust intraband transition. A dense and single-phase TZNMH ceramic was obtained by spark plasma sintering with high hardness (HV 0.1 =31.6 GPa) which remained above 30 GPa even after 60 h exposure at 1800 °C in Ar environment. This high hardness of TZNMH ceramic is believed to arise from the strong hybridization between metals and boron, as revealed by density functional theory calculations. This study demonstrates that high-entropy boride ceramics can be used as ideal high-temperature structural component with high thermal emissivity.

Serine-based monosubstituted acetylene monomers were synthesized and polymerized with rhodium zwitterion catalyst in THF to afford optically active polyacetylene derivatives (LPA and DPA) and corresponding racemic polyacetylenes (RPA) with moderate molecular weights in good yields. All of the substituted polyacetylenes (SPA) were characterized by FT-IR, NMR, GPC, UV-Vis spectroscopy, circular dichroism (CD) spectroscopy, and TGA. LPA and DPA were soluble in common organic solvents and possessed single-handed helical conformation according to their intense Cotton effect and large specific rotations, while RPA presented random coiled polymer chain. The characterization results showed that helical structure of these SPAs was stabilized by intra- and intermolecular hydrogen bonding between the substituents which played a significant role in creating and maintaining the helix. Further, the infrared emissivity properties of them at wavelength of 8 to 14 μm were investigated at room temperature. Consequently, the LPA and DPA exhibited lower infrared emissivity values than RPA, which came down to 0.632 and 0.616. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015 , 132 , 41210.

The rapid development of high performance detection technology promotes the innovation of stealth technology moving towards the direction of multi-band compatibility, but suffers great challenges. Especially for the widely used radar detection and infrared detection, how to overcome the contradiction between their corresponding stealth materials and develop high-performance stealth materials with microwave-infrared compatible property is extremely urgent. Herein, flexible cellular reduced graphene oxide aerogels modulated by antimony tin oxide (ATO/rGO) have been synthesized by self-assembly, which demonstrate excellent microwave-infrared stealth compatibility. Remarkably, the aerogel exhibits dual-absorption in microwave stealth caused by strong interface polarization, achieving the maximum reflection loss (RL) of −40.92 dB at 11.36 GHz coupled with another absorption peak of −19.82 dB at 16.64 GHz and a broadest effective absorption bandwidth of 9.8 GHz covering the X band and Ku band, which can be verified by electromagnetic finite element method simulation. Moreover, trace amount of loss components ATO in conductive network structure guarantee the low infrared emissivity (0.383) and thermal insulation synchronously, which is the key to compatibility with infrared stealth. The light ATO/rGO aerogels demonstrate the great prospect for anti-detection and security protection, providing a novel approach for multispectral compatible stealth.

Low-emissivity and highly transparent coatings are of considerable interest for applications requiring simultaneous infrared radiation control and optical transparency. However, transparent polymer matrices typically exhibit relatively high intrinsic infrared emissivity, while the incorporation of low-emissivity fillers often leads to a loss of optical transparency, making it difficult to balance these properties. In this work, a highly transparent polyurethane (PU) matrix was prepared via a prepolymer method, and a multilayer PU/silver nanowire/PU (PU–AgNW–PU) composite coating was fabricated by introducing AgNWs to simultaneously regulate infrared emissivity and optical transmittance. The PU film (40 μm) exhibited an infrared emissivity of 0.65 (8–14 μm) at 80°C. After incorporation of AgNWs, the composite coating showed a reduced infrared emissivity of 0.45 while maintaining visible-light transmittance above 80% (400–700 nm) and haze below 20%. This multilayer structural design provides an effective strategy to balance low infrared emissivity and high optical transparency in PU-based coatings.

Novel chiral N -propargylamide based on stigmasterol (M1, HC CCH 2 NHCOCH 2 CH 2 COO-R, R = stigmasteryl) and achiral N -propargylamide based on pivalic acid (M2) were prepared and (co)polymerized with rhodium zwitterions catalyst in CHCl 3 to afford helical polyacetylenes with moderate molecular weights (8997–26777) in good yields. The polymers were characterized by Fourier transform infrared spectroscopy (FT-IR), 1 H nuclear magnetic resonance ( 1 H NMR), gel permeation chromatography (GPC). Ultraviolet–visible spectroscopy (UV–Vis) and circular dichroism (CD) absorption spectra demonstrated that the as-prepared polymers could form helical structures with a preferential helicity. The formation of hydrogen bonds of poly(M1) in CHCl 3 was investigated according to the solution sate IR spectroscopic data . The single-handed helical conformation and polymerization degree of the new-typed poly( N -propargylamide)s could be controlled by the changing the feed ratio of chiral and achiral monomers . Furthermore, the infrared emissivity values (0.536–0.798) of copolymers were investigated at 8–14 μ m by the Infrared Emissometer.
