The Properties And Application of Graphene oxide

What exactly is graphene?

Graphene Oxide (graphene dioxide) is graphene. Its color is brown-yellow and it is usually represented as GO. 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. The graphene layer can be expanded up to tens or microns. 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 actually amphiphilic. It shows hydrophilicity along the edges of the sheet, and then hydrophobic properties in 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:

Graphene oxide 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 oxide is easy to functionize and has a high level of controllability. Graphene oxide can effectively disperse materials attached to metals, metal-oxides, high-molecular-polymers, etc., by providing a large surface area.

Graphene dioxide also exhibits excellent physical properties. The coexistence of various functional groups containing oxygen on the base and edge of the sheet framework of graphene allows graphene to be controlled. 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.
