What is graphene dioxide?
The oxide graphene is known as graphene oxide. Graphene oxide is usually abbreviated GO. Its color 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. A single atomic sheet of graphene can expand up to tens or hundreds of microns laterally at any moment. Its structure therefore crosses the usual scales in general chemistry and material science. Graphene is a soft material that has the properties of colloids, films and amphiphilic compounds. Due to its excellent dispersibility in liquids, graphene has been considered a hydrophilic compound for a long time. However, the relevant experimental data shows that graphene is actually amphiphilic. The hydrophilicity of graphene is distributed from the edge 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 and use of graphene oxide

Although the oxidation destroys graphene’s highly conjugated structure, the material still 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. Graphene Oxide, used as a precursor for graphene composite materials and as a support carrier, is highly functionalizable and controllable. It provides a large surface area for dispersing metals and metal oxides as well as high molecular weight polymers.

Graphene dioxide also exhibits excellent physical properties. The coexistence of oxygen-containing functions groups at the base and edge of the graphene framework allows graphene to be modulated by the type and number. The material is versatile and 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.
