Lightweight, ultrathin, and flexible electromagnetic interference (EMI) shielding materials are highly needed to protect electronic devices and to halt cross-talk between devices and device components. In this work, we investigated that a two-dimensional (2D) transition metal carbonitride, Ti3CNTx MXene, with a moderate electrical conductivity, provides a higher shielding effectiveness (SE) compared with more conductive Ti3C2Tx and metal foils of the same thickness. This outstanding shielding performance of Ti3CNTx is achieved by thermal annealing and is governed by an anomalously high absorption of electromagnetic waves (EMWs) in its layered, metamaterial-like structure. This high absorption of EMWs makes Ti3CNTx a potential candidate for flexible and compacted 5G electronics. |
