摘　　要：分别采用溶液聚合、乳液聚合、正相和反相微乳液聚合法合成了不同掺杂、不同电导率(电导率范围10-5～10S/cm)的聚苯胺,测试了导电聚苯胺的电磁学参数和吸波性能。结果证明制得的聚苯胺在2～12GHz范围内有较好的吸波性能,在2～12GHz范围内,雷达波反射率绝对值大于10dB的频宽范围大于7.5GHz,最大吸收率达到30dB。Different doped polyanilines (PANI) with conductivities from 10^-5 S/cm to 10 S/cm) were synthesized by aqueous solution polymerization,emulsion polymerization,microemulsion polymerization and inverse microemulsion polymerization.The electromagnetic properties and microwave absorptivity of the synthesized PANI were tested.It was proved that the composites had good microwave absorptivity at the frequency from 2 GHz to 12 GHz when the absolute radar wave reflection ratio was larger than 10db,the frequency width range was wider than 7.5 GHz,and the maximum microwave absorptivity was 30 dB.
