摘　　要：为提高材料在低频段下的吸波性能,采用化学氧化聚合法和物理共混法制备聚苯胺和羰基铁-聚苯胺复合材料。通过X-射线衍射(XRD)、红外光谱(FT-IR)、矢量网络分析(PNA)等测试手段对材料的物相和性能进行了表征和分析。结果表明:在0～6GHz,羰基铁-聚苯胺复合材料的吸波性能较纯羰基铁有了很大提高,而且其吸收峰向低频区移动,当导电聚苯胺的质量分数为0.06时,其吸波性能最佳,最大吸收峰值为-39.1dB,-10dB以下频宽为1 639MHz。In order to increase the absorbing ability in the lower band, the polyaniline（PANI） and carbonyl iron-polyaniline composites were prepared by chemical oxidative polymerization and physical blending. The phase and performance of materials were analyzed and characterized by XRD, FT-IR and PNA. Results showed that the absorption ability of the carbonyl iron-polyaniline composites was advanced in 0 6 GHz. Meanwhile, the absorption peak of composites moved toward low frequencies. When the mass fraction of PANI was 0.06, it had the best wave-absorbing property, of which the maximum absorption could reach --39.1 dB and the bandwidth below --10 dB was 1 639 MHz.
