In this work, TiC, which has a loosely packed accordion-like structure in transition metal carbide (MXene) form, is fabricated and adsorbed by three metal ions (Fe/Co/Ni). The electromagnetic interference (EMI) shielding performance of TiC and TiC:Fe/Co/Ni films is researched in detail, demonstrating that the EMI shielding effectiveness can be improved by adsorbing by Fe/Co/Ni ions because the metal ion adsorbing can improve the absorption efficiency via electromagnetic wave scattering. The studied TiC:Fe/Co/Ni films can be used as good EMI shielding materials for communications, electronics, military, and other applications.

在这项工作中，制备了呈过渡金属碳化物（MXene）形式的具有松散堆积的手风琴状结构的TiC，并使其吸附三种金属离子（Fe/Co/Ni）。详细研究了TiC以及TiC:Fe/Co/Ni薄膜的电磁干扰（EMI）屏蔽性能，结果表明，通过Fe/Co/Ni离子吸附可以提高EMI屏蔽效能，因为金属离子吸附可通过电磁波散射提高吸收效率。所研究的TiC:Fe/Co/Ni薄膜可用作通信、电子、军事及其他应用的优良EMI屏蔽材料。
