Abstract Currently, the demand for electromagnetic wave (EMW) absorbing materials with specific functions and capable of withstanding harsh environments is becoming increasingly urgent. Multi-component interface engineering considered an effective means to achieve high-efficiency EMW absorption. However, modulation has not been fully discussed great potential in field In this study, multi-component tin compound fiber composites based on carbon (CF) substrate were prepared by electrospinning, hydrothermal synthesis, high-temperature thermal reduction. By utilizing different properties substances, rich heterogeneous interfaces are constructed. This effectively promotes charge transfer enhances interfacial polarization conduction loss. The SnS/SnS 2 /SnO /CF abundant have exhibit excellent absorption at a loading 50 wt% epoxy resin. minimum reflection loss (RL) − 46.74 dB maximum bandwidth 5.28 GHz. Moreover, composite coatings exhibited long-term corrosion resistance Q235 steel surfaces. Therefore, study provides strategy design complex environments.

Abstract Construction of built‐in electric field (BIEF) in nanohybrids has been demonstrated as an efficacious strategy to boost the dielectric loss by facilitating oriented transfer and transition charges, thus optimizing electromagnetic wave absorption property. However, specific influence BIEF on interface polarization needs explore thoroughly strength should be further augmented. Herein, several systems incorporated Mott–Schottky heterojunctions hollow structures are designed constructed, where bimetallic zeolitic imidazolate framework employed derive Cu‐ZnO heterojunctions, hierarchical enriched introducing structure reduced graphene oxide. The well‐established “double” verified theoretical calculation engineering can regulate conductivity, enhance relaxation effectively. Especially, there always coexisted both enhanced charge separation reversed distribution this BIEF, boosting polarization. Attributing synergy well‐matched impedance amplified loss, obtained hybrids exhibited superior (reflection −46.29 dB ultra‐wide effective bandwidth 7.6 GHz at only 1.6 mm). This work proves innovative model for dissecting mechanisms pioneers a novel advanced absorbers through enhancing BIEF.

Optical-electromagnetic compatible devices are urgently required in intelligent building monitors and cross-band protection. Meanwhile, the insufficient systematicness semi-empirical attempts significantly limit prosperity of materials, causing enormous challenges for deviceization material database construction. Herein, systematical component-deviceization-machine learning prediction-array construction strategy is attempted to solve bottleneck issues. A luminance-triggered camouflage-monitoring-protection triune integrated modular unit (IMU) hierarchically encapsulated simultaneously achieve efficient anti-electromagnetic interference (EMI), light-absorbing, quick gradient-colorization response. Moreover, an illumination intensity dataset a surrogate model based on fully connected neural network fitting (FCNN-fitting) constructed, which accurately predicts light-absorbing property IMUs can be instructional selection. The specifically assembled into 4*4 array, aiming at multi-scenario application programmable display, camouflage pattern, surface conformality, rapid replaceability. This work paves path provides promising optical-electromagnetic compatibility genetics-deviceization-array systematization.

Dual magnetic particles-modified carbon materials have great potential in terms of ultrathin thickness (≤ 2 mm) and super electromagnetic wave (EMW) absorption -70 dB). Herein, using CoFe-metal-organic framework (MOF)-derived CoFe/Co@NC heterostructures composed hollow CoFe nanospheres, solid Co nitrogen-doped (NC) nanosheets, we demonstrate how the dual particles regulate response behavior heterostructure thus steer efficient EMW performance. That is, inherits an ultra-strong reflection loss (R L) -73.8 dB at 1.78 mm. The effective bandwidth (EAB) value is also available up to 5.4 GHz. Moreover, computer simulation technology (CST) simulations reveal good radar stealth effect heterostructures. Experimentally, outstanding due a large number heterointerfaces, conductive networks nanoparticles, which bring considerable interface polarization, conduction loss, characteristics. These findings underscore importance synergy induced by for steering absorbers.

Cellulose aerogels, as a novel class of carbon-based materials, exhibit immense potential in the field microwave absorption (MWA) due to their biocompatibility, low density, unique porous structure, and tunable architecture. However, development multi-dimensional components with specialized heterogeneous structures, which are based on cellulose remains significant challenge. This 0D/1D/3D structural configuration facilitates electromagnetic properties favorable impedance matching. The Schottky contact at ZnO/Ni interface, particular, induces strong interfacial polarization, design results multiple heterointerfaces. Density functional theory (DFT) calculations reveal that barrier causes band bending, facilitating directed migration electrons interface formation an internal electric field, thus significantly accelerating multipolar relaxation process. As anticipated, CCMC/ZnO@Ni aerogel exhibits minimum reflection loss (RLmin) value -64.0 dB 13.9 GHz thickness 2.0 mm, its effective bandwidth (EAB) reaches 4.9 GHz. work gives valuable guidance inspiration for materials composed dimensional gradient holds great application wave (EMW) attenuation.
