Abstract
The rapid growth in communication and advanced electronics in modern society has made electromagnetic interference (EMI), resulting in EM pollution becoming a serious issue, prompting research on new materials for effective EMI shields that are a lightweight alternative to metals. Here, we present a multilayered Ti3C
$_{2} \text {T}_{\text {X}}$
MXene-(poly(3,4-ethylenedioxythiophene)-polystyrene sulfonate (PEDOT:PSS) composite for EMI shielding. The multilayered accordion-like structure is blade-coated to prepare the EMI shield. Extensive material characterization confirms the high quality of the shield material. The MXene composite with 20% of MXene in conducting polymer shows 34 dB shielding performance and a green index (GI) value of ~0.5 indicating a higher absorption-based shielding compared to conventional metal shields.
