Abstract
Methods of preparing dispersions of carbon-based materials are disclosed herein. In some embodiments, a method comprises exposing the carbon-based material to an atmosphere comprising between about 0.5% v/v and about 5.0% v/v of oxygen for a selected time at an oxidation temperature to obtain a thermally oxidized material; and dispersing the thermally oxidized material in a liquid medium.

A method of preparing a dispersion of a carbon-based material, comprising:
- exposing the carbon-based material to an atmosphere comprising between about 0.5% v/v and about 5.0% v/v of oxygen for a selected time at an oxidation temperature to obtain a thermally oxidized material;
- and
- dispersing the thermally oxidized material in a liquid medium.
A method of preparing a dispersion of a carbon-based material, comprising:
- determining a threshold temperature at which a specific carbon-based material begins to oxidize in a given atmosphere;
- exposing the carbon-based material to the given atmosphere at an oxidation temperature less than the threshold temperature for a time sufficient to at least partially oxidize the carbon-based material;
- and
- dispersing the at least partially oxidized carbon-based material in an aqueous medium.
