Electromagnetic Interference Shielding of 2D Transition Metal Carbide (MXene)/Metal Ion Composites
Xuefeng Xia, Quanlan Xiao
Abstract
In this work, Ti3C2, which has a loosely packed accordion-like structure in transition metal carbide (MXene) form, is fabricated and adsorbed by three metal ions (Fe3+/Co2+/Ni2+). The electromagnetic interference (EMI) shielding performance of Ti3C2 and Ti3C2:Fe3+/Co2+/Ni2+ films is researched in detail, demonstrating that the EMI shielding effectiveness can be improved by adsorbing by Fe3+/Co2+/Ni2+ ions because the metal ion adsorbing can improve the absorption efficiency via electromagnetic wave scattering. The studied Ti3C2:Fe3+/Co2+/Ni2+ films can be used as good EMI shielding materials for communications, electronics, military, and other applications.
