Herein, cobalt ferrite was in-situ growth on multi-walled carbon nanotubes (MWCNT) and then impregnated with SiO 2 to synthesize a CoFe 2 O 4 /MWCNT/SiO 2 (CFMS) composite layer, and finally, CFMS was hot-pressed with Balsa veneer to prepare a multi-layer radar absorption structure (MRAS). By varying the molar ratios of Co/Fe and the number of impregnations, abundant heterogeneous interfaces and multiple loss mechanisms can be generated, resulting in excellent EMW absorption for MRAS. The MRAS is investigated to exhibit excellent performance with a minimum reflection loss (RL min ) of -37 dB and an effective absorption bandwidth (EAB) of 7.6 GHz at a thickness of 3 mm. On one hand, the microscopically precise adjustment can significantly enhance the polarization relaxation and conduction loss capabilities, thus improving the electromagnetic energy dissipation efficiency; on the other hand, the multi-layer structural composites on the macroscopic level can synergistically optimize the impedance matching and reduce the reflections while promoting the multilevel scattering. Meanwhile, this multi-layer network structure makes the mechanical properties of the material significantly improved, with the elastic modulus (E b ) and fracture toughness (δ b ) of 5973.79 MPa and 46.49%, fully reflecting the design advantages of the structural-functional integration.
