A Review on recent progress in polymer composites for effective electromagnetic interference shielding properties- Structures, Process, Sustainability approaches

Abstract

The rapid proliferation and extensive use of electronic devices have resulted in a meteoric increase in electromagnetic interference (EMI), which causes electronic devices to malfunction. The quest for the best shielding material to overcome EMI is boundless. This pursuit has taken different directions, right from materials to structures to process up to the concept of sustainable materials. The emergence of polymer composites has substituted the metal and metal alloy-based EMI shielding materials due to their unique features such as lightweight, excellent corrosion resistance, superior electrical, dielectric, thermal, mechanical, and magnetic properties that are beneficial for suppressing the EMI. Therefore, polymer nanocomposites are an extensively explored EMI shielding materials strategy. This review focuses on recent research developments with major emphasis on structural aspects and processing in enhancing the EMI shielding effectiveness of polymer nanocomposites with their underlying mechanisms and some glimpses on the sustainability approaches taken in this field is deeply reviewed.
