Overview of Nanostructured Materials for Electromagnetic Interference Shielding

Abstract

Nanotechnology has accelerated in the past decades, and many nanomaterials have been discovered and reviewed. These materials are being employed in many commercial applications. EMI shielding applications primarily employ intrinsically conducting polymers, carbon-based fillers, and inorganic-based nanoparticles to impart high-end properties. Carbon-based nanomaterials include materials such as carbon black, carbon nanofiber, graphene, and nanotubes. These materials have the advantage of tunable properties necessary to absorb or reflect EMI waves. This chapter reviews different nanomaterials employed as fillers, as well as matrices for shielding applications.
