Abstract
Embodiments of the present disclosure describe a method of preparing a colloidal solution comprising preparing a salted aqueous solvent and dispersing a graphitic material in the salted aqueous solvent. Embodiments of the present disclosure further describe a method of treating a graphitic material comprising agitating a graphitic material in a salted aqueous solvent and removing residual chemical species to obtain a treated graphitic material. Embodiments of the present disclosure also describe a colloidal solution comprising a liquid medium and a treated graphitic material dispersed in the liquid medium sufficient to form a colloidal solution.

A method of preparing a colloidal solution, comprising:
- preparing a salted aqueous solvent, wherein the salted aqueous solvent includes sodium hypochlorite and sodium bromide;
- and
- dispersing a graphitic material in the salted aqueous solvent, wherein the graphitic material includes one or more of few-layer graphene nanoplatelets, few-layer graphene, graphene nanosheets, graphene powder, graphene nanoribbons, carbon nanotubes, carbon spheres, and fullerenes.
A method of treating a graphitic material, comprising:
- agitating a graphitic material in a salted aqueous solvent containing sodium hypochlorite and sodium bromide, wherein the graphitic material includes one or more of few-layer graphene nanoplatelets, few-layer graphene, graphene nanosheets, graphene powder, graphene nanoribbons, carbon nanotubes, carbon spheres, and fullerenes;
- and
- removing residual chemical species to obtain a treated graphitic material.
A colloidal solution, comprising:
- a liquid medium;
- and
- a treated graphitic material dispersed in the liquid medium sufficient to form a colloidal solution, wherein the treated graphitic material is a graphitic material treated in a salted aqueous solution,
- wherein the graphitic material includes one or more of few-layer graphene nanoplatelets, few-layer graphene, graphene nanosheets, graphene powder, graphene nanoribbons, carbon nanotubes, carbon spheres, and fullerenes,
- wherein the salted aqueous solution comprises sodium hypochlorite and sodium bromide.
