A decade after the first report, the family of two-dimensional (2D) carbides, nitrides and carbonitrides (MXenes) includes structures with 3, 5, 7, or 9 layers of atoms in a variety of ordered or solid solution forms, including high-entropy systems. Dozens of MXene compositions have been produced, resulting in MXenes with mixed or uniform surface terminations. MXenes have shown useful and tunable electronic, optical, mechanical, and electrochemical properties, leading to applications ranging from optoelectronics, electromagnetic interference shielding, and wireless communication to energy storage, catalysis, sensing, and medicine. This lecture will present a brief overview of relations between structure, composition, properties and applications of MXenes with the focus on transparent and freestanding conducting films for plasmonic, shielding and electronic applications. The challenges and research directions will be discussed. |
