Graphene is one of the most promising materials for future electronic devices due to its unique electronic, mechanical, and thermal properties. However, graphene’s electrical conductivity is still relatively low compared to other materials like silicon or. This low conductivity can be improved by functionalizing graphene using various chemical and physical methods.

One common method for functionalizing graphene is through the addition of functional groups such as hydroxyls, carbons, and nitrogen-containing groups. These functional groups can alter the structure and electronic properties of graphene, making it more conductive. For example, adding an oxygen atom to the surface of graphene can increase its electronegativity, leading to increased electrical conductivity.
Another method for functionalizing graphene is through the application of magnetic fields. The presence of magnetic domains in graphene can facilitate the transfer of charge between layers, which can improve its electrical conductivity. For instance, applying a magnetic field to graphene has been shown to significantly improve its electrical conductivity, making it more suitable for use in electronic devices.
In addition to functionalization, another way to improve graphene’s conductivity is through the use of high-performance catalysts. Catalysts can interact with the electrons in graphene and facilitate their movement, which can improve its electrical conductivity. For example, a metal-based catalyst that chemically modifies graphene has been shown to significantly improve its electrical conductivity.
