One-dimensional (1D) microwave absorbers have been verified to have a predominant morphology due to their significant anisotropy, large surface area, and great dielectric attenuation compared to other microstructures. Consequently, in this research, novel 1D mesoporous MoO₂/C heteronanowires have been designed through an in situ facile synthesis process. As well as their attractive morphology, building multiple interfaces for polarization between MoO₂ and carbon, inducing dipole polarization of MoO₂ and constructing conductive networks among nanowires endow the composites with outstanding dielectric dissipated properties, allowing excellent microwave absorption (MA) performance. Therefore, at the appropriate filling condition of 25 wt%, the MoO₂/C nanowire-paraffin achieved a minimum reflection loss of −47.6 dB at 11.1 GHz and a bandwidth of 3.8 GHz in the range of 9.9–13.7 GHz with a thickness of 2 mm, thus it has the potential to be a lightweight candidate of microwave absorbing material.

通过设计一维介孔MoO ₂ / C杂化杂散线获得出色的介电损耗

一维（1D）微波吸收器由于具有显着的各向异性，较大的表面积以及与其他微结构相比大的介电衰减性，因此已被证明具有主要的形貌。因此，在这项研究中，通过原位简便的合成工艺设计了新颖的一维中孔MoO ₂ / C杂纳米线。除了具有吸引人的形态外，还为MoO ₂和碳之间的极化建立了多个界面，从而引起MoO _2的偶极极化。并且在纳米线之间构建导电网络使复合材料具有出色的介电耗散性能，从而具有出色的微波吸收（MA）性能。因此，在25 wt％的适当填充条件下，MoO ₂ / C纳米线石蜡在11.1 GHz处的最小反射损耗为−47.6 dB，在9.9–13.7 GHz范围内的带宽为3.8 GHz，厚度为2毫米，因此它有可能成为微波吸收材料的轻量级候选者。
