Abstract: Provided is a method, comprising: providing a solution of delaminated MXene material and a first ionic intercalant; and contacting the solution with a second ionic intercalant so as to exchange the first ionic intercalant and the second ionic intercalant so as to give rise to flocculated portions of the MXene material and a supernatant that comprises the first ionic intercalant and the second ionic intercalant. Also provided is a MXene dispersion, comprising a plurality of portions of single-layer and/or few-layer MXene dispersed in a solvent, the solvent comprising a first ionic intercalant and a second ionic intercalant. Also provided is a stable MXene dispersion, comprising a plurality of portions of single-layer and/or few-layer MXene dispersed in a solvent, the solvent comprising an ionic intercalant, the ionic intercalant optionally being present in supersaturated form.
