With the proliferation of the use of wireless communication technologies, lightweight, easily fabricated EMW absorbers are in great demand for commercial and stealth applications. In this paper, well-defined Cu₂O microcubes were successfully transformed into Cu₉S₅@MoS₂ hollow microboxes by a facile hydrothermal process through a template-directed in situ vulcanization/complexation synergistic reaction. The MoS₂ nanosheets loaded on the microboxes exhibited a high 1T phase ratio. Compared to pure MoS₂ nanosheets, Cu₉S₅@MoS₂ is advantageous in building conducting networks and interfacial polarization due to its good structure. The composite of Cu₉S₅@MoS₂ with paraffin showed good EMW absorption performance at 40 wt%. By adjusting the MoS₂ loading, the attenuation and impedance coefficients can be further optimized, with an optimized R_Lmin of −52.2 dB at 2.1 mm and an EAB of 4.7 GHz.

随着无线通信技术的广泛使用，商业和隐形应用对轻质、易于制造的电磁波吸收器有着巨大的需求。在本文中，通过模板引导的原位硫化/络合协同反应，通过简单的水热过程，将明确的Cu ₂ O微立方体成功转化为Cu ₉ S ₅ @MoS _{2空心微盒。}装载在微型盒上的MoS ₂纳米片表现出高1T相比。与纯MoS ₂纳米片相比，Cu ₉ S ₅ @MoS ₂由于其良好的结构，在构建导电网络和界面极化方面具有优势。_{Cu 9} S ₅ @MoS ₂与石蜡的复合物在40 wt%时表现出良好的EMW吸收性能。通过调整MoS ₂负载，可以进一步优化衰减和阻抗系数，优化后的R _Lmin在2.1 mm处为-52.2 dB，EAB为4.7 GHz。
