Abstract
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 EMI 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.
