What is Graphene Oxide?
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. A single atomic sheet of graphene can be expanded up to tens or microns in size. Graphene oxide’s structure spans 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 long been considered a hydrophilic compound. However, experimental evidence shows that graphene dioxide is actually amphiphilic. It exhibits hydrophilicity along the edges of the sheet, and then a hydrophobic distribution in the middle. The graphene-oxide layer can be used at the interface as a surfactant to reduce energy. Its hydrophilicity has been widely acknowledged.

Application of Graphene Oxide:

The graphene oxide class is an important graphene based material. 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 oxide is easy to functionize and has a high level of controllability. It provides a large surface area for dispersing metals and metal oxides as well as high molecular weight polymers.

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 a wide range of 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.
