摘要: Abstract Electromagnetic interference shielding efficiency (SE) of the mixtures polyaniline (PAN) and conducting powders such as silver (Ag), graphite, carbon black is measured in frequency range from 10 MHz to 1 GHz by using ASTM D4935-89 technique. The SEs are 20 dB 50 dB, which agree with theoretical values obtained a good-conductor approximation. system increase increasing DC conductivity. For mixture emeraldine base form PAN Ag powder doped hydrochloric acid, SE iElectromagnetic is46 with70 μm thickness. Chemical doping samples induces SE. model accounting for discussed. effects multilayer on presented.6 presented.
