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 in size. 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 long been considered a hydrophilic compound. Graphene oxide, according to relevant experiments, is amphiphilic. It shows hydrophilicity along the graphene sheet’s edge, and 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.

The application Graphene Oxide:

It is an important class graphene based materials. Although the oxidation destroys graphene’s highly conjugated structure, it retains its layered structure and special surface characteristics. 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 support carrier, is highly functionalizable and controllable. When compounding with metals or metal oxides and high molecular-weight polymers, graphene oxide can provide a large surface area that will effectively disperse and prevent agglomeration of the materials.

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 a wide range of applications. Surface modification of graphene-oxide composite materials has many applications. This includes polymer composite materials as well as inorganic compound material.

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