Transition metal carbide (MXene) have been considered as an effective EMI shielding material since EMI shielding effectiveness of MXene was published in 2016. MXenes are a family of 2D transition metal carbides, nitrides, and carbonitrides with the general formula Mn 1XnTx (n = 1, 2, or 3; M = transition metal, e.g. Ti, Nb, Mo; X = C and/or N; T = surface termination, e.g. –OH, –F, –O). Unlike other 2D materials, MXenes offer an attractive combination of high electronic conductivity (~5000 S/cm), hydrophilicity, and processability. However, still it is lack of understanding EMI shielding behavior at the atom-scale thickness because it is hard to make uniform atom-thick film. In this presentation, we present the EMI shielding behavior of MXene thin film with atom-level thickness, which were prepared through a self-assembly method. It reveals that MXene is very good for ultra-thin film shielding applications. |
