Dispersions of Two-Dimensional Titanium Carbide MXene in Organic Solvents

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 by measuring the concentration and absorbance spectra of MXene in organic solvents as well as correlating the concentration to solvent physical properties, such as surface tension, boiling point, and polarity index.…
