研究了导电聚合物聚苯胺(PAni)/聚苯乙烯(PS)微/纳米复合材料的电磁波吸收特性. 随掺杂态PAni在复合材料中的含量增加, 复合材料电导率和PAni/PS复合板的吸波能力随之提高. PAni的微观形貌对吸波性能有影响, 纤维形貌PAni要比颗粒形貌PAni具有更好的吸波特性. 经过优化后, 厚度为1.80 mm的掺杂态PAni/PS微/纳米复合材料雷达波反射率小于-10 dB的频宽达6 GHz(11.6—17.6 GHz)
The electromaganic wave absorbing property of Polyaniline (PAni) / Polystylene (PS) blends were studied. The results indicated that The conductivity and electromagnetic wave absorbing property of PAni/PS blends increased with the increasing content of the doped PAni. Doped PAni with fibrous morphology had better electromagnetic wave absorbing property than that of PAni with nonfibrous morphology. The frequency breadth of the reflectivity below -10dB was 6GHz（11.6~17.6 GHz）by optimization of the electromaganic parameters of the PAni/ PS micro/nano-blend.
