Sir,

The best solvent relates to dispersity of GO and that depends on the oxygen functional group. More oxygen content leads to higher disersity in water, ethanol, acetone or DMF. Mostly, its 1-4 mg GO per one mL water can form well dispersion.

Thanks anupma, can u shed some light on fullerenes dispersibility ?

For fullerene, any polar solvents and toluene can be preferred.

But while mixing fullerene and carbon nanotubes ( both single & double walled)in polar solvents like milique water, the particles are pelleted without achieving a dispersion. What to do ?

Hello Kunal,

the dispersibility/solubilization of nanocarbons (fullerenes, nanotubes, graphene, graphene oxid, ...) depends on various parameters. Fullerenes (C60) can be easily dispersed in toluene. In the case of nanotubes and graphene there are different ways (e.g. noncovalent and covalent functionalization) to get quite good dispersions or even true solutions (polyelectrolytes). However, in case of polydisperse materials such as nanocarbons, the dispersibility always depends on the physical nature (e.g. shape and size) and the chemical nature (e.g. defect density or functionalization). For nanocarbon mixtures these parameters can heavily vary. Another important factor you need to consider is the stability of such dispersions over time. For more information please check:
