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.
