Key findings demonstrate that lower SiC content induces localized stress concentrations near particle polar regions, while higher fractions form interconnected high-stress networks (>800 MPa) due to reduced interparticle spacing and stress bridging effects.

A peak strength-ductility synergy occurs at 10 % SiC, while 20 % SiC shows severe embrittlement with rapid crack network percolation.

This design strategy enables gradual impedance matching from the surface and promotes multiple internal reflections within the foam structure, thereby significantly enhancing the absorption of incident electromagnetic waves at the X-band frequency range (8.2–12.4 GHz). We systematically investigated the influence of foam thickness, MWCNTs concentration, cell size, and their stacking order on the total shielding effectiveness (EMI SE), as well as on its absorption and reflection components. While EMI SE was relatively unaffected by stacking sequence, the energy dissipation pathways could be precisely tuned, favoring either absorption or reflection. Notably, the structure with a gradient from large to small cell sizes, combined with a conductive film, achieved over 40 dB of EMI SE at 12.4 GHz, primarily driven by absorption. The results demonstrated that spatial control of foam cell structure and integration of reflective layers provide an effective route for high-performance, absorption-dominant EMI shielding.
