Based on recent advancements, the emission of electromagnetic radiation has become a serious issue of electromagnetic interferences. These electromagnetic interferences comprise of various undesirable emission of radiation that can create unwanted deprivation of equipment or structure performance. If these complications remain unresolved can create extreme damage to the security operation or communication system of several electronic devices. Various studies have been made to resolve these problems. In past years, electrically conductive polyaniline has attained a unique position due to the prosperity of its features. The absorption of microwave and EMI shielding characteristics of the electrically conductive polyaniline can be described in the relation of great electrical conductivity with strong relaxation and, polarization effects due to the existence of stronger bonds or localized charges. In the present article, the advancement in electromagnetic interference shielding with the use of nanosized polyaniline particles and their derivative nanocomposites is discussed by various parameters such as the size of the particle, absorption properties, magnetic properties, reflective properties, electrical conductivities, and dielectric properties. The electromagnetic absorption performance of conducting polyaniline nanocomposites associated with dielectric nanomaterials (graphene) and magnetic materials (γ-Fe₂O₃) are widely discussed. The most appropriate polyaniline-based nanocomposites can be identified by this context. Due to increasing demand of electrically conductive polyaniline for shielding materials, it is considered to be review for better understanding in advancement. This article presents recent electromagnetic interference shielding materials knowledge of nanosized polyaniline and their nanocomposites as well as their possibilities and challenges.
