Abstract

Abstract: High performance electromagnetic interference (EMI) shielding materials with ultra‐low density, excellent flexibility with comprehensive nature are highly demanded for wearable electronics, aeronautic, industries, medical, and research facilities. To address these requirements, the metal‐carbon based polymer composites have been fabricated by simple and scalable synthesis techniques. Combining the effect of multiple scattering with absorption, a high shielding efficiency of up to 29 dB for 0.1 mm is achieved. Selective architects of Ag/Cu nanoparticles along with two‐dimensional conducting sheets of MWCNT/rGO form multiple scattering structures in poly(vinylidene fluoride) matrix, prepared by facile solvent cast technique. The paper discusses the preparation of the composites, studies on morphological aspects, and concludes with a study on EMI shielding in the frequency region between 8 and 12 GHz.
