Two-dimensional titanium carbide (Ti3C2Tx) MXene has attracted tremendous attention due to its excellent potential applications in a variety of fields, such as energy storage, advanced composites, and membranes. However, its potential is greatly limited by the fact that pristine MXene only disperses well in polar solvents and its degradation in them. Even though several approaches that enable the dispersing of MXene in nonpolar organic solvents by surface modification have been reported, they are either too complex, time consuming, or not scalable. We report here a simple and scalable approach that can quickly (< 20 min) disperse MXene in commonly used nonpolar organic solvents, such as toluene. With the assistance of its surface capping ligand, MXene stayed colloidally stable over a month without noticeable degradation. This approach opens the door to solution-process MXene in the other nonpolar world.
