Graphene oxide, also known as GO, is a single layer of carbon atoms arranged in a hexagonal lattice structure. It has gained significant attention in recent years due to its unique properties and potential applications in various fields such as electronics, energy storage, and biomedicine.

One of the main advantages of graphene oxide is its high surface area. Its square-potential hexagonal structure allows for a large number of surface electrons to be available for interaction with other materials, which can lead to enhanced electronic and thermal conductivity. Additionally, GO has a very low cost per unit mass compared to other commonly used materials like silver or gold, making it an attractive option for various industries.
Despite its promising properties, graphene oxide is not completely soluble in water. This is because of its hydrophobic nature, meaning that it repels water molecules. However, there have been some recent developments in the field that suggest that graphene oxide may become more soluble in water under certain conditions.
For example, a study published in the journal Physical Review Letters in 2017 found that graphene oxide may interact with water molecules through hydrogen bonding. The researchers attributed this behavior to the presence of two types of hydrogen bonds in the GO sheet – hydrogen bonds between adjacent layers of the sheet and hydrogen bonds within individual layers. These hydrogen bonds could potentially increase the solubility of GO in water by weakening the intermolecular forces that hold it together.
Another study published in the same journal in 2019 suggested that graphene oxide may become more soluble in water at higher temperatures and pressures. The researchers found that increasing the temperature from room temperature to 400°C increased the solubility of GO in water by 1-2 orders of magnitude.

These findings suggest that graphene oxide may become more soluble in water under certain conditions. However, it’s important to note that more research is needed to fully understand the behavior of graphene oxide in water and to determine whether this solubility increase will generalize to all forms of graphene oxide. Further investigation is needed to fully harness the potential benefits of GO in various applications and to minimize any potential drawbacks associated with its solubility in water.
