“…An innovative approach toward designing high-performance EMI shields by fabricating a stratified double-percolated architecture of PS/PVDF/MXene nanocomposites has been proposed by Wang et al where the S-PS/PVDF/M 12 nanocomposite (0.45 mm thick) exhibited EMI SE of 32.0 dB within the X-band while the H-PS/PVDF/M 12 nanocomposite (1.35 mm thick) exhibited 36 dB SE at a frequency of 10.51 GHz. They ascribed the chief influence on the SE to the enhanced absorption effectiveness being credited to the improved EC and robust multiple reflections along with less dipolar polarization loss . A look at the afore-discussed works established that the thickness, number of layers, conductivity, structural morphology, density, and other undiscussed properties of materials aimed at EMI shielding application greatly influence the EMI SE ultimately.…”

Electromagnetic interference (EMI) shielding effectiveness (SE) systems have received immense attention from researchers owing to the rapid development in electronics and telecommunications, which is an alarming matter in our modern society. This radiation can damage the performance of EM devices and may harmfully affect animal/human health. The harmonious utilization of magnetic alloys and conducting but nonmagnetic materials (such as carbon/graphene) is a practical approach toward EMI SE. This review is not exhaustive, although it is comprehensive and aimed at all materials for EMI SE especially graphene-based polymeric composites. It encompasses multifunctional and functional structural EMI shields. These materials comprise polymers, carbons, ceramics, metals, cement composites/nanocomposites, and hybrids. The accessibility of abundant categories of carbon-based materials in their microscale, nanoscale, and quantum forms as EMI shields as polymer–carbon, cement–carbon, ceramic–carbon, metal–carbon, and their hybrids, makes them receive much attention, as a result of their unique amalgamation of electrical, magnetic, dielectric, thermal, and/or mechanical properties. Herewith, we have discussed the principles of EMI shields along with their design and state of the art basis and material architecture along with the drawbacks in research on EMI shields.
