| Abstract Scope |
MXenes are 1-nanometer-thick 2D sheets of transition metal carbides and nitrides, such as Ti<sub>3</sub>C<sub>2</sub>, V<sub>2</sub>C, Nb<sub>2</sub>C, Ta<sub>4</sub>C<sub>3</sub>, made via top-down selective etching and exfoliation, making MXenes suitable for large-scale production. MXene nanoinks are hydrophilic and have colloidal stability with negative zeta potential (–50 mV), which facilitates their processing for use with other materials, such as metal and ceramic powders, to either coat the particles with MXenes or design assemblies for electronic devices. MXenes have high electrical conductivity at the individual flake and MXene film levels. Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub>, for instance, reaches > 10,000 S/cm with a breakdown current density of 1.2 × 108 Acm-2. In this presentation, we will discuss our latest progress on the self-assembly of MXenes on various metals and ceramics to produce desired assemblies for use in different processing and sintering routes, including electronics and additive manufacturing. |
