Abstract

The relationships between the electrical conductivity and the microwave absorption properties of flaky FeSiCr/paraffin (FFSC/P) composites were studied. When the filler loading reached the percolation threshold, the FFSC/P absorber had better electromagnetic parameters, reflection loss, and absorption bandwidth. With a filler loading of 30 wt%, the FFSC/P absorber exhibited a strong reflection loss of −44.36 dB in the C-band (4−8 GHz) and an absorption bandwidth of 5.08 GHz covering the whole X-band (8−12 GHz). This work has demonstrated a route for the materials design of high-performance microwave absorbers.

利用渗流理论原理对片状FeSiCr/石蜡复合材料优良的微波吸收性能进行了调优

研究了片状FeSiCr/石蜡（FFSC/P）复合材料的电导率与微波吸收性能的关系。当填料加载达到渗透阈值时，FFSC/P吸收体具有较好的电磁参数、反射损耗和吸收带宽。当填充量为30 wt%时，FFSC/P吸收体在c波段（4 ~ 8 GHz）的反射损耗为- 44.36 dB，在整个x波段（8 ~ 12 GHz）的吸收带宽为5.08 GHz。这项工作为高性能微波吸收材料的设计提供了一条途径。
