Abstract Carbon-based aerogels derived from biomass chitosan are encountering a flourishing moment in electromagnetic protection on account of lightweight, controllable fabrication and versatility. Nevertheless, developing facile construction method component design with carbon-based for high-efficiency wave absorption (EWA) materials broad effective bandwidth (EAB) strong yet hits some snags. Herein, the nitrogen-doped magnetic-dielectric-carbon aerogel was obtained via ice template followed by carbonization treatment, homogeneous abundant nickel (Ni) manganese oxide (MnO) particles situ grew carbon aerogels. Thanks to optimization impedance matching dielectric/magnetic components aerogels, (Ni/MnO-CA) suggests praiseworthy EWA performance, an ultra-wide EAB 7.36 GHz minimum reflection loss (RL min ) − 64.09 dB, while achieving specific 253.32 dB mm −1 . Furthermore, reveals excellent radar stealth, infrared thermal management capabilities. Hence, high-performance, easy fabricated multifunctional nickel/manganese oxide/carbon have application aspects protection, electronic devices aerospace.

Abstract Microwave absorbing materials (MAMs) characterized by high absorption efficiency and good environmental tolerance are highly desirable in practical applications. Both silicon carbide carbon considered as stable MAMs under some rigorous conditions, while their composites still fail to produce satisfactory microwave performance regardless of the improvements compared with individuals. Herein, we have successfully implemented compositional structural engineering fabricate hollow SiC/C microspheres controllable composition. The simultaneous modulation on dielectric properties impedance matching can be easily achieved change composition these composites. formation structure not only favors lightweight feature, but also generates considerable contribution attenuation capacity. With synergistic effect structure, optimized composite exhibits excellent performance, whose strongest reflection loss intensity broadest effective reach − 60.8 dB 5.1 GHz, respectively, its actually superior those most previous studies. In addition, stability tests capacity after exposure harsh conditions Radar Cross Section simulation data demonstrate that from optimization a bright prospect

Abstract Energy‐efficient building materials are eye‐catching for reducing indoor energy consumption via eliminating electromagnetic interference and pollution, controlling the thermal transfer, promoting sunlight harvesting providing a comfortable living environment. To realize broadband microwave shielding, elaborate control of microstructures has showed great potential research direction. By composition regulation structure design with various dimension, synergistic effects including conductive networks, interfacial polarization, magnetic coupling, dipole dielectric‐magnetic synergy, can significantly improve (EM) shielding capacity. Thermal management conversion, storage, radiation, conduction enormous in enhancing sustainability efficiency future buildings. Smart windows able to switch optical transmittance colors, which is contributed saving energy. Herein, this review, recent progress management, smart window field energy‐efficient buildings summarized, from aspects materials, mechanisms, scenarios. Further, main bottlenecks problems discussed, opportunities further highlighted.

Abstract Currently, facing electromagnetic protection requirement under complex aqueous environments, the bacterial reproduction and organic dye corrosion may affect composition micro‐structures of absorbers to weaken their properties. To address such problems, herein, a series CoFe 2 O 4 @BCNPs (cobalt ferrite @ bio‐carbon nanoparticles) composites are synthesized via co‐hydrothermal calcining process. The coupling magnetic cobalt dielectric derived from Apium can endow composite multiple absorption mechanisms matched impedance for effective microwave absorption, attaining bandwidth 8.12 GHz at 2.36 mm an intensity −49.85 dB 3.0 mm. Due ROS (reactive oxygen species) stimulation ability heavy metal ions ferrite, realizes excellent antibacterial efficiency 99% against Gram negative bacteria Escherichia coli . Moreover, loose porous layer surface stacked promote adsorption methylene blue subsequent eliminating, high removal rate 90.37% be also achieved. This paper offers new insight rational design composite's component micro‐structure construct multi‐functional absorber satisfying demand in complicated environments.
