Abstract

A new microwave absorber was formed using stacked polypryrrole nanoparticle-coated nonwoven textiles with surface resistivities from 8.5 ×107 to 3.0 Ω·cm. This microwave absorber showed typical frequency dispersion in both εr' and εr'' in a wide frequency range (1 to 75 GHz). A large reflection loss \dotΓ21 with a wide bandwidth was achieved with εr'' dispersion characteristics.
