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 FeS/SnS@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.
在本工作中，我们采用简单的水热法合成了二硫化亚铁和二硫化锡与多壁碳纳米管（MWCNTs）的复合材料。碳纳米管的引入显著提高了复合材料的介电损耗能力。当FeS/SnS@CNTs在石蜡中的填充率为20 wt%且含量为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。
