Abstract

The construction of multifunctional aerogels with optimized stealth performance remains challenging due to unbalanced dielectric-magnetic properties and limited tunability of porous structures. Herein, we report polymer-based EVA-Fe 3 O 4 -GO (EFG) aerogels via a direct heated cross-linking process and pores modulation engineering. The obtained porous EFG hybrid aerogels construct discontinuous dielectric matrix and optimize dielectric-magnetic synergism, achieving efficient electromagnetic wave absorption. The pores modulation engineering enables precise control over porosity, where regulating NaCl template content modifies pore sizes and densities, forming a hierarchical porous architecture. EFG aerogels…
