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.
