Abstract

A comprehensive overview of the up-to-date research activities targeting electromagnetic interference (EMI) shielding is provided, focusing on the multifunctional polymer nanocomposites (PNCs) reinforced with a variety of conductive fillers. The unique dielectric, magnetic and other physicochemical properties derived from certain morphology-, composition-, and loading-controlled nanostructures for EMI shielding behaviors are elaborated. The conductive fillers including three different categories: carbon, metals, and conductive polymers in the EMI shielding PNCs are discussed together with their synergistic effects on enhancing the EMI shielding property. The enhanced electromagnetic interference shielding effectiveness and mechanisms are discussed with detailed examples and are envisioned to provide rational design of next generation lightweight EMI shielding materials.
