摘要

摘要: 借助导电聚合物和软磁金属良好的电磁波吸收特性, 制备了导电聚苯胺/ 羰基铁粉复合材料。实验中把导电聚苯胺与羰基铁粉以2∶8 的比例制成复合粉, 然后再将复合粉与聚脲粘和剂以2∶8 的比例混合成吸波涂料。检测结果显示, 当聚苯胺电导率为10 ^-2 S/ cm、羰基铁粉平均颗粒尺寸为1～2μm, 在2～12 GHz 的频段范围可获得优于- 10 dB 的吸波性能。分析表明, 这类材料有望发展成宽频、强吸收、可人为设计特殊频段的优良吸波材料。

Abstract: The conductive polyaniline / iron carbonyl powder composite material was prepared based on conductivepolymer and soft magnetic metals , which have very good characteristics of electromagnetic wave absorbing. The conductive polyaniline / iron carbonyl composite powder was prepared under the volume ratio of 2∶8. The composite of wave absorbing dope , which consists of the composite powder and polyurea , was composed under the volume ratio of 2∶8. It indicates that the wave absorbing property of the composite is better than - 10 dB in the frequency range of 2～12 GHz ,while the conductivity of polyaniline was 10^-2 S/ cm and the average size of iron carbonyl powder is 1～2μm. The analysis demonstrates that excellent wave absorbing materials with wide frequency characteristic , strong wave absorption abilityand programmable frequency range could be developed based on this technology.
