2D MXenes for Electromagnetic Wave Absorption

This chapter focuses on the preparation and properties of MXenes, as well as the MA performance of MXene-based materials designed through composition optimization and structure regulation. It presents the preparation method of MXenes. Many methods have been used to fabricate 2D MXenes, including top-down etching-assisted exfoliation and bottom-up synthesis. The chapter also presents the properties of MXenes. It aims to strategies based on components (such as dielectric, magnetism, and multiple loss materials) and micro-/macrostructure manipulation (such as 3D microspheres, fibers, sandwiches, and hierarchical structures). Surface functional group modulation can affect the Fermi energy level and the electrical properties of MXenes. The chapter analyzes the development potential of absorbers based on MXenes. Layered MXene, network-like MXene nanoribbons, porous MXene monolayers, and porous MXene layers are rationally constructed with favorable microstructures and surface states for electromagnetic wave absorption.
