| 英文摘要 | In response to the urgent need for high-performance coatings that simultaneously provide efficient electromagnetic wave (EMW) absorption and long-term corrosion protection in harsh marine conditions, Cu/Ni-MOF@PAN core-shell nanofiber mats are first electrospun and then served as self-templates during high-temperature carbonization into hollow magnetic carbon frameworks (CN-HPCF) embedded with CuNi alloy nanoparticles. The as-obtained CN-HPCF are then dispersed in epoxy and spray-coated with modified TiO2 to create a 155 degrees superhydrophobic, gradient-impedance bilayer. The unique hollow, porous, and multi-level heterogeneous interface structure of CN-HPCF effectively optimizes impedance matching and synergistically enhances various electromagnetic energy dissipation mechanisms, achieving a minimum reflection loss (RLmin) of -43.06 dB and a maximum effective absorption bandwidth (EAB) of 6.4 GHz at 1.9 mm thickness. Radar cross-section (RCS) simulations further confirm the stealth potential on ship-scale platforms of CN-HPCF. The electrochemical impedance spectroscopy (EIS) results show that the coating maintained a high impedance modulus of 5.25 x 10(8) Omega cm(2) at 0.01Hz after being immersed in 3.5 wt% NaCl solution for 30 days. This study thus presents the new integrated absorption-corrosion bi-functional coating that maintains both -43.06 dB microwave absorption and > 10(8) Omega cm(2) barrier performance after 30 days of seawater immersion, offering a new design paradigm where robust corrosion protection is the prerequisite for long-term EMW absorption stability in marine environments. |
