What is graphene dioxide?
Graphene Oxide (graphene dioxide) is graphene. It is usually abbreviated GO. The color of the oxide is brown-yellow. Common products available on the market include powder, flake, and solution. Its properties become more active after being oxidized because the functional groups containing oxygen are increased.
Graphene flakes are made from graphite powder, which has been chemically oxidized and exfoliated. Graphene is an atomic-thick layer that can expand up to tens or microns at a time. Its structure therefore crosses the usual scales in general chemistry and material science. Graphene is a soft material that has the properties of colloids, polymers and films. Due to its excellent dispersibility in liquids, graphene has been considered a hydrophilic compound for a long time. The relevant experimental results have shown that graphene Oxide is in fact amphiphilic. This means it has hydrophilicity at the edge of the sheet and hydrophobic properties towards the center. The graphene-oxide layer can be used at the interface as a surfactant to reduce the energy. Its hydrophilicity has been widely acknowledged.

The application Graphene Oxide:

It is an important class graphene based materials. Although the oxidation destroys graphene’s highly conjugated structure, it retains special surface and layered properties. The introduction of oxygen-containing groups not only makes graphene oxide chemically stable, but also provides surface modification active sites and a larger specific surface area for the synthesis of graphene-based/graphene oxide-based materials. As a precursor and carrier for graphene composite materials, Graphene is oxide has a high level of controllability and can be easily functionalized. In the process for compounding with metals and metal oxides as well as high molecular-polymers and other material, it provides a large surface area that can effectively disperse and prevent agglomeration.

Graphene Oxide also has excellent physical, chemical and optical properties. Due to the coexistence on the edges and base of the graphene sheets of different oxygen-containing functional group, it is possible to control its conductivity. The material has many applications. The material has many applications. Surface modification of graphene-oxide composite materials has many applications. This includes polymer composites, inorganic compound material, and other composite materials.

Graphene oxide is widely used as a semiconductor electronic package due to its excellent properties in terms of electrical, mechanical and thermal properties.
