Abstract
The frequent use of electrical equipment and devices has raised a serious threat to the environment and society in the form of electromagnetic interference (EMI), which not only decreases the competency of instruments but also affects the human health badly. Therefore, to reduce the effect of EMI, materials with high shielding effectiveness (SE) need to be designed. Conducting polymers (CPs) such as polyaniline, polypyrrole, polythiophene, etc., provide high conductivity and dielectric properties and are found to be promising for EMI shielding applications. Further, to enhance its SE, composites based on CPs have been widely studied. In view of this, the present chapter highlights the recent developments in CP composites in EMI shielding. The synthesis and properties of such materials are also discussed in detail. Further, the future scope of CP-based EMI shielding materials has also been discussed in detail.
