Abstract There is an urgent demand for flexible, lightweight, mechanically robust, excellent electromagnetic interference (EMI) shielding materials. Two-dimensional (2D) transition metal carbides/nitrides (MXenes) have been potential candidates the construction of EMI materials due to their great electrical electroconductibility, favorable mechanical nature such as flexibility, large aspect ratios, and simple processability in aqueous media. The applicability MXenes has intensively explored; thus, reviewing relevant research beneficial advancing design high-performance MXene-based shields. Herein, recent progress macrostructure development reviewed, including associated mechanisms. In particular, various structural strategies are highlighted explored. end, difficulties views future growth shields proposed. This review aims drive macrostructures on basis rational high-efficiency utilization MXene.

Abstract Simultaneously developing protective electronics film for multi‐spectra, including the radar, infrared (IR), and visible ranges, both military civilian sectors is extremely challenging. The existing multi‐spectra‐compatible materials mainly concentrate on either radar/IR or IR/visible bands, trailing rapid evolution of advanced devices monitoring electromagnetic signals. Here, it designed fabricated an ultra‐thin MXene‐based composite (20 µm) containing black phosphorus (BP) Ni chains (M‐B‐M(Ni)) with integrated highly efficient thermal IR stealth, light absorption, wave shielding. M‐B‐M(Ni) exhibits low emissivity 0.1, decreasing radiation temperature difference between surrounding environment target device. BP offers a high solar absorptance 80%, which guarantees energy conversion from to heat. Moreover, absorption proportion shielding effectiveness 16% higher than that pure MXene films (68.7%), owing improved magnetic loss by decoration chains. Due combined merits MXene, BP, chains, opens avenue construction multi‐spectra compatible versatile applications in shielding, transformation.

MXene-based thermal camouflage materials have gained increasing attention due to their low emissivity, however, the poor anti-oxidation restricts potential applications under complex environments. Various modification methods and strategies, e.g., addition of antioxidant molecules fillers been developed overcome this, but realization long-term, reliable using MXene network (coating) with excellent comprehensive performance remains a great challenge. Here, hybrid comodified hyaluronic acid (HA) hyperbranched polysiloxane (HSi) is designed fabricated. Notably, presence appreciated HA oxidation sheets without altering infrared stealth performance, superior other water-soluble polymers; while HSi can act as efficient cross-linking agents generate strong interactions between molecules. The optimized MXene/HA/HSi composites exhibit mechanical flexibility (folded into crane structure), good water/solvent resistance, long-term stable capability (with emissivity ≈0.29). reliability (≈8 months) various outdoor weathers scalable coating MXene-coated textile enable them disguise IR signal targets in environments, indicating promise achieved material for camouflage, stealth, counter surveillance.

Abstract Processing transition metal carbides/nitrides (MXenes) inks into large‐area functional coatings expects promising potential for electromagnetic interference (EMI) shielding and infrared stealth. However, the coating performances, especially scalable fabrication techniques, are greatly constrained by flake size stacking manner of MXene. Herein, production highly densified oriented MXene is demonstrated engineering interfacial interactions small flakes with catecholamine molecules. The molecules can micro‐crosslink nanosheets, significantly improving ink's rheological properties. It favors shear‐induced sheet arrangement inhibition structural defects in blade process, making it possible to achieve high orientation densification assembly either or patterned printing. Interestingly, MXene/catecholamine exhibits conductivity up 12 247 S cm −1 ultrahigh specific EMI effectiveness 2.0 ×10 5 dB 2 g , obviously superior most reported materials. Furthermore, regularly assembled structure also endows low emissivities stealth applications. Therefore, ultraefficient emissivity prove feasibility applications aerospace, military, wearable devices.

Structure and material composition is crucial in realizing high electromagnetic interference (EMI) shielding effectiveness (SE). Herein, an ultrathin MXene@AgNW@MoS2 (MAM) composite film that resembles the structure of a pork belly exhibits superior EMI performance was fabricated via vacuum-assisted suction filtration process atomic layer deposition (ALD). The staggered AgNWs form skeletons intersperse MXene sheets to build doped with three-dimensional network structures, which improves electrical conductivity film. Based on optimal dispersion concentration Ag single layers, MXene/AgNW AgNW are alternately vacuum-assisted-filtered obtain laminated structures multiple heterogeneous interfaces. These interfaces generate interface polarization increase reflection scattering, resulting increased (EM) wave losses. On other hand, MoS2 outer nanolayers precisely by ALD effectively increases absorption proportion waves, reduces secondary reflection, stability properties. Ultimately, MAM (a thickness 0.03 mm) five alternating internal layers excellent SE 86.3 dB X-band.
