Chapter 29 - Magnetic nanomaterials for electromagnetic interference shielding application

Abstract

Electromagnetic interference (EMI) is the extensive utilize of transitory power sources and uncontrolled and unfavorable branch of explosive development of electronics. The rapid development and widespread use of electronic devices have led to generation of excessive electromagnetic waves that may harm human safety and affects the operation of other electronic equipment. EMI shielding is the inhibition of the diffusion of EM waves from one area to another by using shield materials. EMI shielding materials are necessary for managing electromagnetic interference to secure the human body. These materials such as graphite, graphene, graphene oxide, graphene nanoplatelets, graphene nanoribbons, graphene nanosheets, carbon black, carbon nanotubes, carbon nanofibers, cobalt, and nickel have antioxidant properties, magnetic properties, ideal conductivity, and superior mechanical, thermal, dielectric and electrical properties for EMI shielding applications. This investigation looks at amalgamation procedures, the protecting attributes of EMI, current audit and investigations, related gadgets on the properties of electromagnetic protecting and microwave devices in recent years. The primary headway part of this exploration is to show the impact of using various synthetic substances to frame specific composites on the electromagnetic properties of the relative segments. At last, future recommendations toward determining fundamental impediments of the most radical EMI protecting strategies were presented.
