摘要：以六水合氯化铁和氯化锌为原料，聚乙二醇 4000 为表面活性剂，采用软模板水热法一步合成了具有空心
结构的 ZnFe 2 O 4 纳米颗粒。采用 XRD、XPS、FE-SEM 和 TEM 对样品的物相和形貌进行了表征，通过振动样品
磁强计（VSM）和矢量网络分析仪测试了样品的静磁性能和电磁参数，并模拟计算了样品的反射损耗，考察了
其吸波性能。结果表明，所制备的 ZnFe 2 O 4 粒径约为 100 nm，分散均匀，具有明显的空心结构，吸波性能优异。
当样品的匹配厚度为 2.7 mm 时，在 12.41 GHz 处获得最小的反射损耗（–42.18 dB）；而当匹配厚度为 3.0 mm 时，
样品的有效吸收带宽（反射损耗≤–10 dB，即吸收率为 90%）最宽，为 2.60 GHz（10.60~13.20 GHz）。

Abstract: Using ferric chloride hexahydrateand zinc chloride as raw materials, polyethylene glycol 4000 as
surfactant, ZnFe 2O 4 nanoparticles with a hollow structure were synthesized in one step by a soft template
hydrothermal method. The phase and morphology of the samples were characterized by XRD, XPS,
FE-SEM and TEM, and the magnetic properties of the samples were investigated by vibrating sample
magnetometer (VSM). A vector network analyzer was used to test the electromagnetic parameters of the
sample, and the reflection loss of the samples was calculated by simulation to study the absorbing
performance of the sample. The results showed that the as-prepared hollow ZnFe 2O 4 had a particle size of
about 100 nm, was uniformly dispersed, and had a clear hollow structure. The absorbing properties were
excellent, when the matched thickness of the sample was 2.7 mm, the minimum reflection loss (RL) at
12.41 GHz was up to –42.18 dB; And when the matched thickness was 3.0 mm, the effective absorption
bandwidth (RL≤–10 dB, 90% absorption rate) was 2.60 GHz (10.60~13.20 GHz).
