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 The excellent performance of electromagnetic wave absorbers primarily depends on the coordination among components and rational design structure. In this study, a series porous fibers with carbon nanotubes uniformly distributed in shape pine leaves are prepared through electrospinning technique, one‐pot hydrothermal synthesis, high‐temperature catalysis method. impedance matching nanofibers structure is optimized by incorporating melamine into spinning solution, as it undergoes gas decomposition during calcination. Moreover, electronic can be modulated controlling NH 4 F content synthesis process. Ultimately, Ni/Co/CrN/CNTs‐CF specimen (P3C NiCrN12) exhibited superior performance, while achieving minimum reflection loss (RL min ) −56.18 dB at thickness 2.2 mm maximum absorption bandwidth (EAB max 5.76 GHz 2.1 mm. This study presents an innovative approach to fabricating lightweight, thin materials exceptional properties wide optimizing three key factors influencing performance.
