Abstract

A composition for stabilizing dispersed particles in an ionically charged solution is disclosed. The composition includes a carbonaceous substrate, the carbonaceous substrate operable to undergo a grafting-to approach for functionalization. The composition also includes a covalently bound stabilizing polymer, the covalently bound stabilizing polymer operable to be prepared as a diazonium salt for grafting to the carbonaceous substrate and a plurality of positively and negatively charged subgroups, the plurality of positively and negatively charged subgroups positioned within the covalently bound stabilizing polymer, where the plurality of positively and negatively charged subgroups are operable to stabilize the dispersed particles amongst positively and negatively charged ions within the ionically charged solution.
