Graphene, a two-dimensional material consisting of carbon atoms arranged in a hexagonal lattice, has been shown to have unique properties and potential applications. One such property is its ability to dissolve in water. However, the extent to which graphene can dissolve in water remains a subject of debate among scientists.

One theory is that graphene may be soluble in water due to its high surface area and hydrogen bonding abilities. Hydrogen bonding occurs when a molecule forms strong bonds with another molecule by the sharing of electrons. Graphene’s hexagonal structure means that it has many sites available for hydrogen bond formation, making it an attractive candidate for water molecules.
However, other theories suggest that graphene may not be soluble in water due to its atomic structure and stability. Graphene consists of individual carbon atoms, which means that each atom can form a single bond with another atom. This could make it difficult for water molecules to form hydrogen bonds with the atoms in the graphene network, leading to resistance to solubility.
Despite these uncertainties, some studies have found that graphene may be soluble in water at relatively low concentrations. For example, a study published in the journal Nature Chemistry in 2018 found that graphene oxide (GO) was soluble in water at concentrations as low as 0.1% in aqueous solutions. Similarly, a study published in the journal Macromolecular Research in 2019 found that graphene nanofibers were soluble in water at concentrations as low as 0.5%.

In conclusion, while there is still uncertainty about the solubility of graphene in water, several studies have suggested that it may be soluble at relatively low concentrations. Further research is needed to fully understand the nature of this behavior and to determine whether graphene can be used as a solvent or rather as a chemical modifier.
