Abstract
Excess usage of electronic devices procures electronic noise, Electromagnetic Interference (EMI) and radio-frequency interference (RFI) which could reduce the life-time of electronic components and disturb the performance of delicate devices. Metals can serve as the EMI shield, but their heavy weight, corrosion response and poor meting out conditions limit their usage in EMI shielding applications. The development of EMI shielding materials leads to certain types of nanocomposites, polymer-based nanocomposites that have better properties as compared to the conventional EMI shielding materials. The emergence of polymer-based nanocomposite replaced the conventional EMI materials due to attractive properties such as flexibility, light-weight, corrosion protection and easy processing. In this review, we will critically study different EMI materials such as metallic, nanocomposites and polymer-based nanocomposite with inclusion of different conductive fillers like metals, metallic nanoparticles (NPs), metal-oxide, CB, CF, CNF, CNTs, graphene, graphene-oxide and dielectric/ magnetic such as TiO2, BaTiO3 / 𝛾-Fe2O3, BaFe12O19, Ni0.8Zn0.2Fe2O4.
