摘要/Abstract

摘要：

采用界面聚合和Pickering乳液聚合相结合的方法制备了具有微米尺寸的中空聚苯胺/Fe₃O₄/炭黑微球复合材料, 研究了其形貌、电磁性能和吸波性能. 结果表明, 中空聚苯胺/Fe₃O₄/炭黑微球的平均粒径约为2.0 μm; 在2~4 GHz范围内的磁损耗主要是自然共振和交换共振, 而在4~18 GHz范围内的磁损耗主要是涡流损耗; 在2~18 GHz范围内, 随着涂层厚度增加, 反射损耗峰向低频方向移动, 当涂层厚度增大到5.0 mm时, 反射损耗曲线出现2个反射损耗峰, 分别位于C波段(4~8 GHz)和Ku波段(12~18 GHz), 说明中空聚苯胺/Fe₃O₄/炭黑微球复合材料可作为特定频段的吸波材料.

Abstract:

Polyaniline(PANI)/Fe₃O₄/carbon black(CB) microspheres with hollow-structure were synthesized through the method of interfacial polymerization and Pickering emulsion polymerization. The morphology, electromagnetic properties, and microwave absorbing properties of these materials were characterized. The results showed that the average diameter of these microspheres was about 2.0 μm. The magnetic loss within 2—4 GHz and within 4—18 GHz of these materials were mainly attributed to natural resonance and exchange resonance and to eddy current loss, respectively. In the measurement frequency range of 2—18 GHz, the microspheres with hollow-structure’s minimum reflection loss(RL) shifted to low frequency with the increase of coating layer thickness. As the coating layer thickness increased to 5.0 mm, two peaks occurred, which respectively located in C band(4—8 GHz) and Ku band(12—18 GHz). It was believed that PANI/Fe₃O₄/CB could be a potential electromagnetic wave absorbing materialin C and Ku bands.
