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.
