Summary: Design and fabrication of electromagnetic interference shielding films with a novel structure is important to eliminate undesirable electromagnetic pollution. However, organizing nanofillers of different dimensions into the structured network of polymer-based EMI shielding composites remains a challenge. In this study, a sandwich structure polyimide composite film with 2D-MXene network and 1D-Silver nanowires (Ag NWs) network was prepared using electrospinning-immersion-hot pressing method. The EMI shielding effectiveness (SE) increased with Ag NWs content, while maintaining flexibility and mechanical robustness. The prepared PI composite film with a sandwich structure showed high EMI SE and less metal content, providing guidelines for high-performance EMI polymeric films in wearable devices and equipment development.

Summary: Simultaneously developing protective electronics film for multi-spectra, including the radar, infrared (IR), and visible ranges, for both the military and civilian sectors is extremely challenging. The existing multi-spectra-compatible materials mainly concentrate on either the radar/IR or IR/visible bands, trailing the rapid evolution of advanced devices for monitoring electromagnetic signals. Here, it is designed and fabricated an ultra-thin MXene-based composite film (20 mu m) containing black phosphorus (BP) and Ni chains (M-B-M(Ni)) with integrated highly efficient thermal IR stealth, visible light absorption, and electromagnetic wave shielding.

Summary: In this study, ice crystals were used as templates for polymerization to obtain polymer precursors with directional channels, and then ternary polymer sponges with oriented pore channels were designed and synthesized using a secondary template method. The study material exhibited a Poisson's ratio of 1.52 and absorbed 5.1 mJ/cm3 energy in a single compression cycle at 25% longitudinal strain. It also showed over 90% absorption efficiency for X-band EM waves at a thickness of 4 mm. The flexibility of polymer molecular chains and the arrangement of oriented pores contribute to its negative Poisson's ratio property, while the conversion of quinone bipolaron to monopolaron structure is key to the loss of EM energy during the absorption process.

Summary: The exploration of electromagnetic wave absorbers with anticorrosion for military targets in harsh environments is a challenging task. In this study, core@shell structure Prussian blue analog-derived NiCo@C, CoFe@C, NiFe@C, and NiCoFe@C were obtained with excellent EM wave absorption performance. Among them, NiCoFe@C achieved a minimum reflection loss of -47.6 dB and an effective absorption bandwidth of 5.83 GHz, covering the whole Ku-band. Additionally, these absorbers showed lower corrosion current density and larger polarization resistance under different corrosion conditions, and the salt spray test had little effect on their absorption performance and surface morphologies.

Summary: Due to the complexity and limited control of conventional microwave-absorption materials (MAMs), the precise regulation of atomically-resolved structures and properties of MAMs remains a challenge. In this study, a series of bimetallic MOFs with precise and controllable conductivity were successfully constructed using the customizable functionality of the MOF platform. The controllability was achieved through the alteration of free-carrier concentration and subtle differences in interlayer displacement or spacing, resulting from atomic tuning. Notably, Cu1.3Ni1.7(HITP)(2) exhibited exceptional absorption strength and wide bandwidth, ranking among the highest reported MAMs.

Summary: Recently, 3D carbon foams have shown their superiority in the field of microwave absorption. However, the preparation processes of traditional graphene foams are complicated and some novel carbon foams lack dielectric property. In this study, a simple win-win strategy is demonstrated to simultaneously construct 3D Co/C foam and decorate its surface with carbon microspheres. The interaction between the host Co/C foams and guest carbon microspheres improves the dispersity of carbon microspheres and Co nanoparticles. Electromagnetic analysis reveals that the optimized sample with moderate carbon microsphere content displays a widened maximum effective absorption bandwidth of 5.2 GHz and a consolidated reflection loss intensity of -67.6 dB. The mechanisms of microwave absorption enhancement are also investigated and discussed. It is believed that this work provides valuable ideas for the development of 3D-foam-based microwave absorbing materials for practical applications.

Summary: Bimetallic metal-organic framework-derived composites have attracted significant attention in electromagnetic wave absorption due to their excellent attenuation capacity. However, integrating multifunctionality within a single material is challenging for microwave absorption materials (MAMs) that need to adapt to various environments. In this study, a multifunctional nanocomposite (CoC@FeNiG-F) is fabricated using an in situ growth strategy, chemical interactions, and microwave irradiation. The MAMs exhibit strong reflection loss and effective absorption bandwidth, benefiting from magnetic-dielectric attenuation, impedance matching, and multiple-reflection loss. Furthermore, the MAMs demonstrate excellent mechanical properties, superamphiphobicity, anticorrosion, flame retardancy, and improved energy harvesting performance in extreme environments. This work provides valuable guidance for designing advanced MAMs with robust adaptability and sustainable energy harvesting performance.
