摘　　要：Fe Cl3掺杂浓 H2 SO4 - PAn材料可合成磁损耗较高、有利于吸收微波的材料 .而 HCl- PAn具有较大的电损耗 ,但吸波性能较差 .我们将两种材料按一定比例混合 ,可以合成出平均衰减为 1 3.37d B、最大衰减为 2 6.70 d B、频宽为 1 0 .34～1 4GHz的很有利于微波吸收的材料 .FeCl 3 doped with strong H 2SO 4-PAn can compose a material with a higher magnetic loss and a good absorbing ability. However, HCl-PAn's electric loss is rather high and its absorption ability is low. HCl-PAn mixed with strong H 2SO 4-PAn-FeCl 3 according to a certain proportion can produce a compound material of good microwave absorption with an average reflection reduction of 13.37 dB and the peak value of 26.70 dB in the range of 10.34~14 GHz.
