Graphene oxide is a unique material that can be viewed as a single monomolecular layer of graphite with various oxygen-containing functionalities such as epoxide, carbonyl, carboxyl, and hydroxyl groups. It is a versatile and incredibly useful nanomaterial that has a wide range of applications in various fields. Some of the most common uses of graphene oxide include:

  • Electronic devices: Reduced graphene oxide can be used in electronic devices such as field-effect transistors and chemical sensors.

  • Energy storage devices: Graphene oxide derivatives saturated by carboxyl groups can be used in energy storage applications.

  • Medicine: Graphene oxide has a number of medical applications. Due to its solubility and broad, flat surface area, it is often used as a drug delivery agent. It can also be used at the site of a cancerous growth to help conduct cancer-killing radiation. Graphene oxides have excellent antibacterial properties and are beneficial for their wound healing and anti-infective characteristics.

  • Coatings: Graphene oxide coatings are used on digital displays, solar panels, and luminescent light sources due to their thinness, transparency, and conductivity.

Overall, graphene oxide is a promising material for graphene-based applications in electronic, optics, chemistry, energy storage, and biomedical fields.
