Abstract

Conducting polyaniline composites can be used as shield material for the control of electromagnetic interference in radio frequency range and at 101 GHz. The conducting composites can also be used for the dissipation of static charge. The conducting composites show a shielding effectiveness in the range of 20 dB to 60 dB depending upon the loading of the conducting polymer in the thermoplastic matrix. The characterization of the conducting polymer was carried by thermogravimetric analysis, spectroscopic techniques. A static decay time of 0.02 sec was observed on going down from 5000 volts to 500 volts.
