Ultrathin 2D Nanomaterials for Electromagnetic Interference Shielding

Along with an enormous interest in nanomaterials, 2D nanomaterials hold great promise for a wide range of applications in the fields of chemistry, condensed matter, material science, and engineering. These 2D nanomaterials should continue to inspire many curiosity-driven discoveries and applications in the fields of supercapacitors, batteries, sensors, catalysis, and electromagnetic interference (EMI) shielding. Although there is a worldwide surge in realizing the fabrication of high-performance EMI shielding materials, EMI shielding is a major challenge to modern electronics and devices as they rely on wireless communications. In recent years, 2D nanomaterials are emerged as the most promising materials for applications in EMI shielding. So far, few 2D nanomaterials including graphene, transition metal carbides, and molybdenum disulfide are tested for application in EMI shielding. Herein, recent progress in 2D nanomaterials for high-performance EMI shielding is reviewed. The developments of thin films, layered and hybrid structures are critically reviewed with an emphasis on the role of size, structure, thickness, and interfacial interactions on the shielding efficiency. The progress covered shows great promise for the technological development of advanced EMI shielding materials for modern portable and other advanced electronic devices.
