Since the discovery of graphene, the quest for two-dimensional (2D) materials has intensified greatly. Recently, a new family of 2D transition metal carbides and carbonitrides (MXenes) was discovered that is both conducting and hydrophilic, an uncommon combination. To date MXenes have been produced as powders, flakes, and colloidal solutions. Herein, we report on the fabrication of ∼1 × 1 cm2 Ti3C2 films by selective etching of Al, from sputter-deposited epitaxial Ti3AlC2 films, in aqueous HF…

It is demonstrated that one fruitful approach to alter the electronic and optical properties of MXenes is to change the nature of the transition metal.

Highly Conductive Optical Quality Solution‐Processed Films of 2D Titanium Carbide

MXenes comprise a new class of solution‐dispersable, 2D nanomaterials formed from transition metal carbides and nitrides such as Ti3C2. Here, it is shown that 2D Ti3C2 can be assembled from aqueous

Environment-Sensitive Photoresponse of Spontaneously Partially Oxidized Ti3C2 MXene Thin Films.

It is shown that partially oxidized MXene thin films containing the in situ formed phase of titanium oxide have a significant photoresponse in the UV region of the spectrum, which makes them attractive materials for photoresistors with memory effect and sensitivity to the environment, as well as many other photo- and environment-sensing applications.

Solution-processed titanium carbide MXene films examined as highly transparent conductors.

It is demonstrated that solution-processed Ti3C2Tx conducting films could open up a new direction for the next generation of transparent conductive electrodes, and have a metallic nature, which makes them suitable as electrodes.

Flexible and conductive MXene films and nanocomposites with high capacitance

This first report (to the authors' knowledge) on MXene composites of any kind, shows that adding polymer binders/spacers between atomically thin MXenes layers or reinforcing polymers with MXenes results in composite films that have excellent flexibility, good tensile and compressive strengths, and electrical conductivity that can be adjusted over a wide range.
