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…

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.
