Electromagnetic Interference Shielding: Electromagnetic Shielding of Monolayer MXene Assemblies (Adv. Mater. 9/2020)

Abstract

In article number 1906769, Yury Gogotsi, Sang Ouk Kim, Chong Min Koo, and co‐workers report systematic experimental and theoretical exploration of the electromagnetic interference (EMI) shielding behavior of two‐dimensional Ti3C2Tx MXene assembled films over a broad range of film thicknesses, monolayer by monolayer. A monolayer assembled film offers ≈20% shielding of electromagnetic waves, while a 55 nm thickness demonstrates 99% shielding, revealing that MXene is the best candidate for lightweight EMI shielding applications.

Recent Progress in Protective Membranes Fabricated via Electrospinning: Advanced Materials, Biomimetic Structures, and Functional Applications

“…This development potentially has various applications, such as, wearable smart electronics for resisting electromagnetic radiation pollution, as shown in Figure 14. [184,185] In addition, UV-resistant materials are also a hot topic for research. Regardless of the traditional textile field and the emerging smart textile field based on electrospinning technology, preventing UV penetration, and ensuring wearing comfort are important issues.…”

2D Materials Decorated with Ultrathin and Porous Graphene Oxide for High Stability and Selective Surface Activity

“…The FHGO layers are obtained by simple chemical treatment of GO, and abundantly bear 0.34-0.44 nm micropores. FHGO layer is directly transferred onto BP or MXene through solutionbased interfacial self assembly, [22,23] resulting in the heterostructures of FHGO_BP and FHGO_MXene. These hybrid materials show high stability and selective surface activity, as demonstrated by their performance in a chemical sensing case study with NO 2 under various humid conditions (17.8%-80% relative humidity or RH).…”

Mechanically Robust Flexible Multilayer Aramid Nanofibers and MXene Film for High-Performance Electromagnetic Interference Shielding and Thermal Insulation

“…With the rapid development of electronic technology, people's lives have become more prosperous, and the accompanying electromagnetic interference (EMI) and radiation will not only affect normal working electronic equipment but also pose a potential threat to human health [1][2][3]. Traditional EMI shielding materials are usually made of metals with the high electrical conductivity, but the widespread application of traditional metal EMI shielding materials is hindered by their stiffness, high density and poor anticorrosive performance.…”
