It is well-known that attractive electromagnetic interference (EMI) shielding performance depends on functional (e.g., electrical and magnetic) fillers structural designs. This paper presents a novel three-layered sandwich structure of poly(vinylidene fluoride) (PVDF)-based nanocomposites, consisting graphene nanoplatelets (GNP), nickel (Ni), carbon nanotubes (CNT). The unique GNP-Ni-CNT exhibited excellent EMI ability due to the several interfaces multilayered with electric loss by...
Lightweight, high-efficiency and low reflection electromagnetic interference (EMI) shielding polymer composites are greatly desired for addressing the challenge of ever-increasing pollution. Lightweight layered foam/film PVDF nanocomposites with efficient EMI effectiveness ultralow power were fabricated by physical foaming.

The development of layered polymer composites and foams offers a promising solution for achieving effective electromagnetic interference (EMI) shielding while minimizing secondary pollution. However, the current fabrication process is largely based on trial error, with limited focus optimizing geometry microstructure. This often results in suboptimal wave reflection use unnecessarily thick samples. In this study, an input impedance model was employed to guide PVDF composite foams. approach...
