Modeling Guided Defect engineering of high-entropy MXenes towards coating and shielding applications

Abstract

The emergence of two-dimensional MXenes, a family of 2D transition metal carbides, nitrides, and carbonitrides, presents a new avenue for exploration in the domain of shielding materials. Discovered in 20111 MXenes have garnered world-wide attention owing to their remarkable properties such as high mechanical strength, excellent electrical conductivity, and thermal stability. These characteristics position MXenes as potential candidates for diverse applications, including energy storage and electromagnetic interference shielding. MXenes are synthesized from their parent 3D MAX phases through selective etching yielding 2D layers of transition metal carbides and nitrides. This etching results in a unique combination of metallic conductivity, hydrophilicity, high aspect ratio, and flexibility. For coatings materials, these properties are particularly pertinent. The mechanical strength and flexibility of MXenes are vital in environments where materials undergo significant mechanical stress. Their thermal stability and corrosion resistance are an essential attribute for materials exposed to harsh conditions. The thermal conductivity of MXenes could facilitate effective heat dissipation, crucial for protecting some components from thermal damage. Furthermore, the tunable chemistry of MXenes allows for the development of materials with desired properties, tailored to specific needs.
