Abstract:	In this study, the electromagnetic interference (EMI) Shielding effectiveness (SE) and the characterization of conductive PVAc-AgNO(3) chelate films are investigated. By adding metal salts AgNO(3) into PVAc matrix, metal chelate polymer with Ag+ ions attached to the function groups of PVAc as the complex structure were prepared. Then the films of the metal chelate polymer were cast and reduced, the silver atoms generated and implanted on the surfaces of the metal chelate films. The SE values of the conductive metal chelate films were measured by far field transmission line method, with frequency ranging from l50KHz-1GHz. The best SE (30dB) was reached by AgNO(3) concentration (w%=15) of the metal chelate films (Rs=5Ω/cm^2 ), a higher SE (35dB) was even attained by double layers films (Rs=IΩ/cm^2) with AgNO(3) concentration w%=30. As confirmed by x-ray and SEM analyses, the conducting network that formed by silver atoms on the surfaces of the reduced films was the dominant path for electron propagation.
