摘要：
Electromagnetic shielding properties at microwave and millimetre waves frequencies of polyaniline composites were studied. The conducting blends showed very low percolation threshold and their electronic properties can be tuned easily with the mass fraction of polyaniline. Measurements on composite materials were performed from 50 MHz to 110 GHz with different techniques using network analysers. Shielding effectiveness from 10 dB to 70 dB with a mass fraction of polyaniline varying from 1% to 40% were found.
