摘要
研制了一种由羰基铁粉和导电聚苯胺（PAn）复合而成的新型宽频带雷达吸波材料．通过扫描电子显微镜（SEM）和透射电子显微镜（TEM）分析其微观组成是羰基铁粉表面包覆聚苯胺；复合吸收剂0．9mm单层吸波涂层在6～18GHz范围内吸收量达5dB．通过设计还可以进一步拓宽频带和增强吸收．这种材料重量较轻、耐腐蚀、频带宽，有望开发成为实用吸波材料。
A new type of broadband radar absorbing material （RAM） was synthesized with carbonyl iron and conduction polyaniline （PAn）. By SEM and TEM analyses the microstructure of the product was carbonyl iron coated by conduction polyaniline, and the single absorbent layer of 0.9 mm with the composite absorbent attenuated about 5 dB microwave in the range from 6 to 18 GHz. The bandwidth could be broadened and the effect of absorbing could be improved by further study. It should be applied as a useful RAM for its lightweight, corrosion resistant and broad-band.
