摘要

导电聚苯胺复合材料可作为屏蔽材料，用于控制射频范围和101 GHz频段的电磁干扰。导电复合材料还可用于静电的耗散。导电复合材料的屏蔽效果在20 ~ 60 dB范围内，这取决于导电聚合物在热塑性基体中的负载。通过热重分析、光谱技术对导电聚合物进行了表征。从5000伏下降到500伏时，观察到0.02秒的静态衰减时间。

Shielding of electromagnetic interference using conducting polymer composites

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.
