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.

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.
