What exactly is graphene?
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 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, polymers and films. Due to its excellent dispersion in water, graphene has long been considered a hydrophilic compound. However, experimental evidence shows that graphene dioxide is actually amphiphilic. It exhibits hydrophilicity along the graphene sheet from its edge to center. The graphene-oxide layer can be used at the interface as a surfactant to reduce the energy. Its hydrophilicity has been widely acknowledged.

Graphene Oxide: An application:

Although the oxidation destroys graphene’s highly conjugated structure, the material still 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. As a precursor and carrier for graphene composite materials, Graphene Oxide is easy to functionize and has a high level of controllability. 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.

The number and type of oxygen-containing groupings are used to modulate the conductivity of graphene. 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.
