The results show that the PAn doped with H_2SO_4 have small electricity wastage and high magnetic wastage, the PAn doped H_2SO_4-FeCl_3 with have highest magnetic wastage and is advantageous microwave absorbing material.

• 发现浓H2SO4掺杂本征态聚苯胺(PAn)所合成材料的电损耗很小、磁损耗较大(相对于HCl-PAn).；FeCl3掺杂浓H2SO4-PAn材料可合成磁损耗较高、基本上有利于吸收微波的材料;
