Abstract

Modern electronic devices need effective shielding from external Electromagnetic Interference (EMI) to function correctly. The Electromagnetic (EM) waves emerging from communication systems and medical devices must be isolated to safeguard humans from exposure. The mechanics of EMI shielding as well as several characterization methods are discussed in this paper. Existing trends and practices of designing, fabrication and use of polymer matrix composites for EMI shielding applications are covered. Several approaches and new solutions for fabricating composites either by modification of filler or matrix are discussed and prominent features of EMI shielding material are also discussed. Conducting polymers such as polyaniline, polypyrrole and polythiophene make them adept for EMI shielding applications. An assessment of the different factors affecting the performance of EMI shielding materials is also presented.
