The development of efficient electromagnetic wave (EMW) absorbing materials relies on rational microstructures and loss mechanisms. This study innovatively proposes a design strategy based micronano structural regulation─heterogeneous interface construction─synergistic optimization fabricates MoC@NiCo layered double hydroxide (LDH) composite material with 3D chrysanthemum-like morphology. petal-like microstructure enhances the multiple reflection scattering effects incident EMWs, while heterogeneous interfaces further stimulate polarization. Meanwhile, density functional theory (DFT) guides regulation polarization conduction synergy for EMW energy attenuation. Experimental results show that material, thickness only 2.4 mm, has minimum (RLmin) -57.9 dB, an maximum effective absorption bandwidth (EABmax) covering 5.4 GHz, encompassing entire C, X, Ku frequency bands. Radar cross-sectional (RCS) testing verifies potential to effectively attenuate EMWs in practical applications. provides theoretical basis method guidance through synergistic conductivity lays foundation meet more stringent application requirements.
