Abstract The previous studies mainly focused on improving microwave absorbing (MA) performances of MA materials. Even so, these designed materials were very difficult to be employed in complex and changing environments owing their single-functionalities. Herein, a combined Prussian blue analogues derived catalytical chemical vapor deposition strategy was proposed produce hierarchical cubic sea urchin-like yolk–shell CoNi@N-doped carbon (NC)-CoNi@carbon nanotubes (CNTs) mixed-dimensional multicomponent nanocomposites (MCNCs), which composed zero-dimensional CoNi nanoparticles, three-dimensional NC nanocubes one-dimensional CNTs. Because good impedance matching attenuation characteristics, the CoNi@NC-CoNi@CNTs MCNCs exhibited excellent performances, achieved minimum reflection loss ( RL min ) −71.70 dB at 2.78 mm Radar Cross section value −53.23 m 2 . More importantly, acquired results demonstrated that presented photothermal, antimicrobial anti-corrosion properties structure, highlighting potential multifunctional applications. It could seen this finding not only generalizable route magnetic NC-CNTs-based MCNCs, but also provided an effective develop improve environmental adaptabilities.

Abstract Aerospace vehicles and electronic devices are often operated in elevated temperature environments, which has led to an increased demand for high‐temperature microwave absorbing materials (MAMs). The absorption properties of MAMs influenced not only by the intrinsic material characteristics but also micro‐, meso‐, macro‐structural configurations composites. This paper reviews recent advancements through a multiscale design approach. Due sensitivity permittivity, tend exhibit reflection behavior at temperatures. Strategies aimed regulating conductivity polarization can enhance impedance matching under these conditions; however, this results unavoidable reduction loss capability. In contrast traditional methodologies, constructed from subwavelength‐scale functional units achieve remarkable anti‐reflection effects discrete unit distribution, thereby significantly optimizing both dielectric capacity matching. Furthermore, equivalent electromagnetic parameters metacomposites intrinsically linked their physical structural attributes. relationship offers novel strategy enhancing performance. It is anticipated that review will provide insightful guidance future explorations into innovative highly efficient MAMs.

Abstract The rapid development of military and civilian electronic communication technology poses a severe challenge to controlling electromagnetic radiation pollution in the low‐frequency microwave band. This study introduces novel one‐step feeding self‐assembly ripening strategy synthesize 1D@2D magnetic microchains (Co@Fe x Co 1‐ OOH, CFC). experimental simulation results show that increasing flux length ordered orientation is very important improve absorption performance 1D absorber. CFC‐LC‐E (long‐chain CFC aligned along electric field direction) prepared based on above characteristics successfully achieves high‐performance effect, with minimum reflection loss value ( RLmin ) −66.4 dB. Notably, it maintains stable against oblique incidence (within 90°) polarizations (transverse transverse magnetic). work offers ideas fabrication absorbers analysis mechanisms.

Abstract The rapid development of wireless communication and infrared (IR) detection technologies has generated an increasing demand for large‐size high‐performance wearable electromagnetic interference (EMI) shielding IR stealth textiles. Herein, meter‐scale MXene/graphene oxide (MG)@monstera nanocellulose (MC) core‐shell nanofiber textiles are fabricated the first time using a multi‐stage cryogenic drying‐assisted coaxial wet spinning assembly strategy, with MG as conductive composite core MC organic skeleton shell. highly aligned shell dense endow nanofibers great toughness ≈39.6 MJ m −3 , strong strength >≈180 MPa, high conductivity 6.4 × 10 3 S −1 . exhibit unprecedented ultra‐broadband EMI performance covering gigahertz terahertz bands, optimal effectiveness up to 84 85 dB in band 8.2–26.5 GHz 0.3–1.5 THz, respectively, at only 185 µm thick. Superb near‐ mid‐IR ranges is also achieved, benefitting from their good heat resistance low emissivity. Furthermore, demonstrate excellent dyeability, flame retardancy, Joule heating, stress‐sensing properties. Such scalable prepared superior comprehensive have broad application prospects future smart protective devices.
