摘要：
A new microwave absorber was formed using stacked polypryrrole nanoparticle-coated nonwoven textiles with surface resistivities from 8.5 x 10(7) to 3.0 Omega.cm. This microwave absorber showed typical frequency dispersion in both epsilon'(r) and epsilon ''(r) in a wide frequency range (1 to 75 GHz). A large reflection loss Gamma(21) with a wide bandwidth was achieved with epsilon ''(r) dispersion characteristics. (C) 2011 The Japan Society of Applied Physics
