Two-dimensional titanium carbide (Ti3C2Tx) MXene has attracted a great deal of attention in the research community and has already showed promise in numerous applications, but only its dispersions in aqueous solutions have previously been available. Here we show that Ti3C2Tx can be dispersed in many polar organic solvents, but the best dispersions were achieved in N,N-dimethylformamide, N-methyl-2-pyrrolidone, dimethyl sulfoxide, propylene carbonate, and ethanol. The dispersions were examined…

Hydrolysis of 2D Transition-Metal Carbides (MXenes) in Colloidal Solutions.

It is shown that water and related processes of MXene hydrolysis play the main role in the phenomena leading to complete transformations of 2D titanium carbide MXenes into titania in aqueous environments.

Universal Ligands for Dispersion of Two-Dimensional MXene in Organic Solvents.

Chemically Stabilized and Functionalized 2D‐MXene with Deep Eutectic Solvents as Versatile Dispersion Medium

2D transition metal carbides and nitrides, namely MXenes, are normally synthesized in acidic solutions and are delaminated in basic solutions. This results in versatile materials with unique

Colloidal Behaviors of Two-Dimensional Titanium Carbide in Natural Surface Waters: The Role of Solution Chemistry.

The colloidal properties and stability of Ti3C2Tx MXene were explored in aquatic systems at the first time, considering the roles of solution chemistry conditions (e.g., pH, ionic types and strength).

An investigation into the factors governing the oxidation of two-dimensional Ti3C2 MXene.

It was found that aqueous solutions of Ti3C2Tx MXene can be chemically stable for more than 39 weeks when the storage temperature (-80 °C) is sufficiently low to cease the oxidation processes, and if the Ti3 C2Tx flakes are dispersed in ethanol, the degradation process can be significantly delayed even at 5 °C.

Facile Solution Processing of Stable MXene Dispersions towards Conductive Composite Fibers

This study offers a new processing route for the development of novel MXene‐based architectures, devices, and applications by using MXene processed via the solvent exchange (SE) approach, while the traditional redispersion approach has proven ineffective for fiber processing.

Herein we develop a chemical etching method to produce porous two-dimensional (2D) Ti3C2Tx MXenes at room temperature in aqueous solutions. The as-produced porous Ti3C2Tx (p-Ti3C2Tx) have larger

Solvent exfoliation of electronic-grade, two-dimensional black phosphorus.

Overall, this study shows that stable, highly concentrated, electronic-grade 2D BP dispersions can be realized by scalable solvent exfoliation, thereby presenting opportunities for large-area, high-performance BP device applications.

Solvent exfoliation of transition metal dichalcogenides: dispersibility of exfoliated nanosheets varies only weakly between compounds.

This work shows that solution thermodynamics and specifically solubility parameter analysis can be used as a framework to understand the dispersion of two-dimensional materials.

Intercalation and delamination of layered carbides and carbonitrides.

Intercalation of hydrazine, and its co-intercalation with N,N-dimethylformamide, resulted in increases of the c-lattice parameters of surface functionalized f-Ti3C2, from 19.5 to 25.48 and 26.8 Å, respectively.

Antibacterial Activity of Ti₃C₂Tx MXene.

The antibacterial properties of single- and few-layer Ti3C2Tx MXene flakes in colloidal solution were investigated and showed a higher antibacterial efficiency toward both Gram-negative E. coli and Gram-positive B. subtilis compared with graphene oxide (GO), which has been widely reported as an antibacterial agent.

Graphene Dispersion and Exfoliation in Low Boiling Point Solvents

One of the problems with solvent exfoliation of graphene is that the best solvents tend to have high boiling points and so are difficult to remove and can present problems for flake deposition and
