摘要

在这项工作中，我们采用直接的水热法合成了二硫化铁和二硫化锡与多壁碳纳米管（MWCNTs）的复合材料。碳纳米管的加入显著提高了复合材料的介电损耗能力。当石蜡中 FeS2/SnS2@CNTs 的填充率（20 wt%）为 40% 时，有效吸收带宽为 3.28 GHz，而最小反射损耗（RL）值高达 -39.2 dB，对应的厚度仅为 1.4 mm。这项工作揭示了这种材料在厚度薄、吸收强和质量轻方面的潜在研究价值。

High-performance electromagnetic wave absorption in FeS2/SnS2@multi-walled carbon nanotube composites with honeycomb-shaped structure

In this work, we synthesized composites of ferrous disulfide and tin disulfide with multi-walled carbon nanotubes (MWCNTs) using a straightforward hydrothermal method. The incorporation of carbon nanotubes significantly enhanced the dielectric loss capability of the composites. When the filling ratio of FeS₂/SnS₂@CNTs (20 wt%) in paraffin was 40%, the effective absorption bandwidth was 3.28 GHz, while the minimum reflection loss (RL) value was as high as −39.2 dB, which corresponded to a thickness of only 1.4 mm. This work reveals the potential research value of this material in terms of thin thickness, strong absorption and light mass.
