以二甲基亚砜（DMSO）为溶剂进行溶液聚合制得聚丙烯腈（PAN）溶液,在此溶液中混入了微米级铁粉后将其压成薄膜,将烘干后的薄膜高温碳化处理制得一种碳基吸波材料。采用X射线衍射（XRD）、扫描电镜（SEM）等手段对材料的成分、形貌、结构进行了表征。采用矢量网络分析仪对该复合材料在2～18GHz频段内的电磁参数进行了测试,并作了微波反射率的数值模拟。研究了碳化温度对材料物相组成和电磁性能的影响以及碳化温度和涂层厚度对材料吸波性能的影响。此种吸波材料是无定形炭和铁的氧化物、铁的氮化物等磁性物质的复合材料,兼有电损耗和磁损耗,具有较好的吸波性能。

Electromagnetic wave absorption material comprised of amorphous carbon and magnetic particles was prepared by heat treatment of polyacrylonitrile（PAN） with ultrafine iron powders dispersed in it.The phase composition and morphology of the material were characterized by X-ray diffraction（XRD） and scanning electron microscopy（SEM）,respectively.Electromagnetic parameters of the composite material were measured in the frequency range of 2-18 GHz by vector network analyzer and the numerical simulation of microwave reflection loss was conducted.The effects of temperature and coating thickness on electromagnetic wave absorption properties were investigated.This kind of absorbing material is a composite material comprised of amorphous carbon and iron oxide,or iron nitride with electric loss and magnetic loss,and has good absorbing properties.
