Carbon-based nanocomposites for EMI shielding: Recent advances

Abstract Carbon is an attractive material for electromagnetic shielding because of the low density and high electrical conductivity of carbon allotropes with dominated sp2 bonds. There are graphite, carbon blacks, multiwalled and single-walled carbon nanotubes, onion-like carbons, pyrolytic carbon, carbon porous monoliths, graphite nanoplatelets, and graphene that are conductive and have been widely investigated. All these materials have been widely researched for their physicochemical properties and potential applications in electromagnetic interference (EMI) shielding applications. This chapter will selectively summarize the recent progress in fabrication and use of carbon allotropes-based nanomaterials for EMI applications. The most promising carbon allotropes for this application will also be reviewed in detail and their performances underlined. Conclusions and perspectives will be presented.
