创新的微观结构设计和合适的多组分策略对于具有强吸收和宽有效吸收带宽(EAB)的先进电磁吸波材料(EAM)仍然具有挑战性。采用简单的水热还原与高温煅烧制备了磁性CoFe/Ni4Zn/FeO/还原氧化石墨烯(rGO)(MR)复合吸波材料,MR复合材料具有丰富的异质界面与多孔结构,通过引入磁性颗粒调节电磁参数、提高阻抗匹配和衰减能力,在12.88GHz时最小反射损耗可以达到-46.15dB,有效吸收带宽高达约6.1GHz(10.64～16.72GHz)。MR复合材料优异的电磁吸波性能归因于三维多孔结构的多重反射、散射和弛豫过程以及界面基质的强界面极化。磁/介电性的多组分复合材料MR具备多种损耗机制,其协同作用能够进一步增强材料的吸波性能。
Abstract：Innovative microstructure design and suitable multi-component strategies remain challenging for advanced electromagnetic absorption materials(EAMs)with strong absorption and wide effective absorption bandwidth(EAB). Magnetic CoFe/Ni_4Zn/FeO/reduced graphene oxide(rGO)(MR)composite absorbing materials were prepared by simple hydrothermal reduction and high temperature calcination. The MR composite materials have heterogeneous interfaces and porous structure. By introducing magnetic particles, electromagnetic parameters can be adjusted, impedance matching and attenuation can be improved. At 12.88 GHz, the minimum reflection loss can reach -46.15 d B, and the EAB is up to about 6.1 GHz(10.64-16.72 GHz). The excellent electromagnetic absorption performances of MR composites are attributed to the multiple reflection, scattering and relaxation processes of the 3D porous structure and the strong interface polarization of the interface matrix. The synergistic action of multiple loss mechanisms in the magnetic/dielectric multi-component composite materials can further enhance the electromagnetic wave absorption performance.
