摘要

With the modernization and rapid development of wireless technology, telecommunication and various electromagnetic devices have been used extensively and evolved significant increase in electromagnetic (EM) radiation. These EM radiations affect the normal functioning and reliability of individual electronic devices by interfering with its performances. Besides these, it has an adverse effect on living beings. Several shielding materials have been developed to resolve the electromagnetic interference (EMI). Traditional shielding materials, such as metals while effective, often suffer from limitations like weight, corrosion, and costCarbon nanocomposites. Carbon nanocompositesNanocomposites, on the other hand, offer a compelling alternative due to their lightweight, corrosion resistance, and tunable electrical and magneticMagnetic properties. In the present chapter, we have studied carbon-based nanocompositesCarbon-based nanocomposites for EMI shielding, their potential to revolutionize shielding materials due to their unique properties and versatility.
