摘要：

The paper reports the designing and development of conducting polyaniline composites which show a shielding effectiveness of 4-58 dB against electromagnetic interference at 101 GHz range, depending upon the loading of the conducting polyaniline in polystyrene and polymethylmethaacrylate matrix. The composites can be used for the dissipation of static charge. A static decay time of the order of 0.11-0.02 s for the conducting polyaniline composites is observed when the charge is reduced from 5000 to 500 V. (C) 2002 Elsevier Science Ltd.
