Multilayered MXene-PEDOT:PSS Composite for Electromagnetic Interference Shielding

Abstract

The rapid growth in communication and advanced electronics in modern society has made electromagnetic interference (EMI) and resulting EM pollution a serious issue, prompting research on new materials for effective EMI shields that are a lightweight alternative to metals. Here, we present a multi-layered Ti3C2TX MXene-PEDOT: PSS composite for EMI shielding. The multi-layered 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 value of ~ 0.5 indicating a higher absorption-based shielding compared to conventional metal shields.
