Abstract

Heterojunction and morphology control assume a significant part in adjusting the intrinsic electromagnetic properties of absorbers to acquire outstanding microwave absorption (MA) performance, but this still faces huge challenges. Herein, FeS₂/C/MoS₂ composite with core–shell structure was successfully designed and prepared via a multi-interface engineering. MoS₂ nanosheets with 1T and 2H phases are coated on the outside of FeS₂/C to form a porous interconnected structure that can optimize the impedance matching characteristics and strengthen the interfacial polarization loss capacity. Remarkably, as-fabricated FCM-3 harvests a broad effective absorption bandwidth (EAB) of 5.12 GHz and a minimum reflection loss (RL_min) value of −45.1 dB. Meanwhile, FCM-3 can accomplish a greatest radar cross section (RCS) reduction value of 18.52 dB m² when the detection angle is 0°. Thus, the convenient computer simulation technology (CST) simulations and encouraging accomplishments provide a novel avenue for the further development of efficient and lightweight MA materials.

具有核壳结构的FeS2/C/MoS2多界面工程，具有优异的微波吸收性能

异质结和形态控制是调节吸波器固有电磁特性以获得优异的微波吸收性能的重要因素，但这仍然面临着巨大的挑战。通过多界面工程，成功地设计并制备了具有核壳结构的FeS2/C/MoS2复合材料。在FeS2/C表面涂覆1T相和2H相的MoS2纳米片，形成多孔互联结构，优化了阻抗匹配特性，增强了界面极化损耗能力。值得注意的是，FCM-3的有效吸收带宽（EAB）为5.12 GHz，最小反射损耗（RLmin）值为- 45.1 dB。同时，当探测角为0°时，FCM-3最大雷达截面（RCS）降低值为18.52 dB m2。因此，方便的计算机模拟技术（CST）模拟和令人鼓舞的成就为进一步开发高效轻量化的MA材料提供了新的途径。图形抽象
