Abstract
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.
