Graphene vs. Graphene Oxide: What's the Difference?
Graphene is a single layer of carbon atoms in a hexagonal lattice; Graphene Oxide is graphene with oxygen and other functional groups attached.
Graphene is a single layer of carbon atoms arranged in a two-dimensional hexagonal lattice, known for its exceptional strength, conductivity, and thinness. Graphene Oxide (GO) is a derivative of graphene, featuring various oxygen-containing groups, which alters its properties, making it less conductive but more soluble in water.
Graphene is highly conductive, both electrically and thermally, and is one of the strongest materials known. It is used in a variety of applications, from electronics to composites. Graphene Oxide, on the other hand, has reduced electrical conductivity due to the disruption of its sp2 bonding networks by oxygen groups, but its increased solubility makes it useful in fields like material science and biomedical applications.
Graphene is hydrophobic, meaning it repels water, which limits its use in certain applications. Graphene Oxide is hydrophilic, meaning it can interact with water, which expands its usability in aqueous solutions and for certain chemical processes.
Graphene can be produced through methods like mechanical exfoliation or chemical vapor deposition, which yield a pure form of graphene. Graphene Oxide is typically produced by oxidizing graphite, a process that introduces oxygen-containing groups to the graphene structure.
Graphene has potential applications in high-speed electronics, sensors, and advanced composites due to its unique properties. Graphene Oxide is used in areas like drug delivery, water purification, and as a precursor for producing other graphene-based materials.
