Abstract

Electrical conductivity and electromagnetic interference (EMI) shielding effectiveness at microwave (200-2000 MHz) and X-band (8-12 GHz) frequency range of polyaniline (PAni) composites were studied. It has been observed that EMI shielding of conductive polyaniline, (PAni)-ethylene vinyl acetate composites increases with the increase in the loading levels of the conductive polymer doped with dodecylbenzene sulfonic acid. The result indicates that the composites having higher PAni loading (>23% can be used for EMI shielding materials and those with lower PAni loading can be used for the dissipation of electrostatic charge.
