摘要：
In order to allow electronic components to coexist without harmful electromagnetic interference (EMI) it is necessary to develop new shielding and absorbing materials with high performance and a large operating frequency band. Conducting polymer composites have been found to be Suitable for EMI shielding and for the dissipation of electrostatic charge. In the present study polyaniline-polyurethane (PANI-PU) composite was considered for these applications. The microwave absorption, microwave reflection and EM I shielding properties of PANI-PU composite is evaluated both at S-band and X-band frequencies. The material is found to have good microwave,absorption and is a potential candidate for EMI shielding applications. (C) 2008 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
