Abstract
Provided are methods of stabilizing MXene compositions using polyanionic salts so as to reduce the oxidation of the MXenes. Also provided are stabilized MXene compositions.
Claims19
A method of stabilizing MXene compositions against oxidation, comprising:
- contacting a polyanionic salt that comprises at least one of a polyphosphate, a polyborate, and a polysilicate to a MXene composition having at least one layer having first and second surfaces and an edge, the contacting being performed so as to give rise to a corresponding MXene composition having at least one layer having first and second surfaces and an edge having associated therewith the at least one of a polyborate, a polyphosphate, or a polysilicate.
A composition, comprising:
- a MXene composition having at least one layer having first and second surfaces and an edge;
- and
- at least one polyanion associated with the edge, wherein the polyanion is a polyborate, a polyphosphate, or a polysilicate.
