Graphene Oxide, 2-5 Layer, SA: 420 m2/gr
Graphene oxide (GO) is produced by oxidizing graphite using strong oxidizers, resulting in a compound composed of carbon, oxygen, and hydrogen in variable ratios. The structure and properties of graphene oxide depend on the specific synthesis method and degree of oxidation. Despite these variations, GO retains the layered structure of the original graphite.
Key Characteristics:
- Number of Layers: 2-5 layers
- Surface Area: 420 m²/g
Advantages of Graphene Oxide (GO):
Graphene oxide has a significant advantage over other 2D materials, such as graphene, due to its ability to disperse easily in solutions, allowing for processing at high concentrations. This property makes GO suitable for various applications, including:
- Optical coatings
- Transparent conductors
- Thin-film batteries
- Chemical-resistant coatings
- Water purification
- And many other advanced uses.
