“…Besides, stringent processing requirements are inevitable to match the irregular structure of the targets. Another promising alternative configuration refers to the composite with fillers of polar oxides [13], metamaterials [14], carbon [15], conjugate polymers [16], photonic crystal [17], and phase-change materials [18]. As a matter of fact, they are normally macroscopically discontinuous and necessitate external binders or film shapes to achieve structural shaping, whereas the high emissivity additives tend to offset their intrinsic superiority [19].…”

Advanced scenario-adaptable infrared (IR) stealth materials are crucial for creating localized closed thermal environments. Low emissivity over the broadest possible band is expected, as is superior mechanical deformability. Herein, we report a series of Ti-based MXenes with naturally low emissivity as ideal IR shielding materials. Over a wavelength ranging from 2.5 to 25 μm, Ti3C2TX film delivers an average emissivity of 0.057 with the lowest point of 0.042. Such a low emissivity coupled with outstanding structural shaping capability is beyond the current grasp. The reflection-dominated mechanism is dissected. Also, some intriguing scenarios of IR stealth for wearable electronic devices and skin thermal control are demonstrated. This finding lights an encouraging path toward next-generation IR shielding by the expanding MXene family.

“…[4][5][6] Low infrared emitting coatings or thermal insulation fabrics are usually applied on the target surface to achieve infrared stealth. [7][8][9][10] However, this approach may be powerless in the case that significant amounts of heat generated in the target, which may cause the target temperature too high and consequently the target may be overheated to stop working or be detected due to the increase of infrared radiation. In addition, low infrared emitting coatings (e.g., aluminum powder) generally tend to have high visible brightness and glossiness, which inevitably limits their application in visible wavelength stealth.…”

Phase change materials (PCMs) have been particularly concerned as infrared stealth functional materials due to their superior thermal management capability. However, traditional PCMs usually behave rigid solid or flowing liquid states with fixed transition temperature, greatly limiting their application especially in multi-band stealth and multiple scenes. Herein, an intrinsically flexible self-healing phase change film used for synchronous visual/infrared stealth for the first time is designed and constructed. The phase change film possesses a solid-solid phase transition behavior with adjustable transition temperature (from 38.8 to 51.1 °C) and enthalpy (from 79.7 to 116.7 J g −1 ), long-term cycling stability (500 cycles), and outstanding flexible and selfhealing performance. Remarkably, the phase change film can be customized with different colors and various configurations to exhibit attractive visual stealth functions in multiple scenes. Additionally, owing to phase transition property, this phase change film can possess a thermal management capability and behave infrared stealth performance for objectives at various temperatures. Combining the above unique functions, the intrinsically flexible self-healing phase change film developed in this work may show great potential for applications in the synchronous visual/infrared stealth across a wide range of scenarios and temperatures.

Poly (o‐anisidine) Encapsulated K₂ZrO₃ Nano‐core based Gelatin Nano Composites: Investigations of Optical, Thermal, Microcrystalline and Morphological Characteristics

A series of Gelatin/poly‐o‐anisidine coated K2ZrO3 polymer nanocomposite were fabricated by varying the poly‐o‐anisidine (POA) coated K2ZrO3 viz 0, 1, 2, and 4 wt% using the solvent casting method. From High‐resolution transition electron microscopy (HRTEM) results it is cleared that the average size of the prepared nanoparticles and polymer coated nanoparticles are around 18–20 and 95–100 nm respectively, and the polymer coated nanoparticles are spherical in shape, and form a core shell. The phase purity and microcrystalline behavior of the prepared nano particles, POA coated nanoparticles and gelatin nanocomposites were analyzed by using X‐ray diffraction (XRD). Scanning electron microscope [SEM] and energy dispersive spectroscopy [EDX] were employed for the analysis of the surface morphology and the elemental composition of the prepared nanoparticles and nanocomposites. Fourier transform infrared spectroscopy (FTIR) was used to assess the physical interactions between the components in nanocomposites. The thermal stability and effect of polymer coated nanoparticles on glass transitions temperatures were studied by using Thermo‐gravimetric analysis (TGA) and differential scanning calorimetry (DSC) respectively. From UV–Visible spectroscopy studies it is clear that, with increase in POA coated K 2ZrO 3 nanoparticles concentration from 0 to 4 wt % in a gelatin matrix, the band gap energy (Eg) value drops from 4.13 to 2.16 eV, and the refractive index rises from 1.529 to 3.25.
