Abstract Scope |
About 50 stoichiometric MXene compositions and dozens of solid solutions and high-entropy structures with up to 9 different elements with various terminations have been made since our first report on Ti3C2Tx in 2011 [1]. The number of possible compositions is infinite if one considers solid solutions and combinations of surface terminations. New subfamilies of in- and out-of-plane ordered MXenes, oxycarbides, 2D borides and silicides further expand this family of chemically diverse 2D materials based on transition metals. MXenes have propelled us into an era of computationally driven atomistic design of 2D materials. They possess electronic, optical, mechanical, and electrochemical properties that differentiate them from other materials. They can be used as 2D building blocks for assembling (multi)functional materials and devices that will power future technologies [2]. They can also be rolled into scrolls to create 1D structures, which complement the array of 2D MXene materials. In this talk, I’ll discuss the emerging chemical synthesis methods of MXenes, the effect of synthesis on composition and properties, and the assembly of MXenes into functional films and coatings. Co-assembly with graphene and other nanomaterials will also be discussed, and the prospects for applications of MXene-based materials in various fields, including electronics, healthcare, and electrochemical energy storage, will be outlined.
