What is graphene dioxide?
Graphene oxide, also known as graphene oxide, is an oxide made from graphene. Its name is GO and it is brown-yellow. It is available in powder, flake, or solution. Oxidation causes the product to have oxygen-containing functional chains that increase in activity, making it more active than graphene. The properties of the product can be further improved by various reactions using oxygen-containing function groups.
Graphene oxide flakes can be made from graphite after it has been chemically oxidized and exfoliated. The graphene oxide atomic layer is one that can expand to many tens of millimeters in size. Because of this, it is able to transcend the traditional scales in materials science and general chemical chemistry. You can consider graphene dioxide a unique type of soft material. It has characteristics similar to polymers, colloids and films as well as amphiphilic molecules. Due to its high water dispersibility, graphene dioxide has been considered hydrophilic. But, evidence from experiments shows that grapheneoxid is in fact amphiphilic. The graphene sheet’s edges show hydrophilicity. Graphene dioxide can be used as an interface surfactant to reduce energy. It is known for its hydrophilicity.
Application graphene dioxide:
While graphene oxide, an important class of graphene based materials, is oxidized to remove the high-conjugated structure, but it retains special surface characteristics and a layered structure. 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. The precursor to the production of graphene-based, composite materials is graphene dioxide. It can be functionalized easily and it has excellent controllability. When compounding with metals and metal oxides or high molecular plasticmers it provides a large surface area for dispersing the materials attached and preventing agglomeration.
Grapheneoxid also has exceptional physical, chemical and optical properties. Because of its coexistence with various oxygen-containing groups at the edges and base of graphene sheet framework graphene oxide is able to be controlled. The types and numbers of these oxygen-containing groups can be used to modify its conductivity as well as its band gap. There are many uses for this material. Graphene dioxide is a novel carbon material that has excellent performance. The material features a high surface specific area and numerous surface functional group. The wide variety of uses for grapheneoxid composite materials (including polymer composites and inorganic compounds materials) has led to the development of a new research field: surface modification.
Graphene oxide is widely used because it has excellent mechanical, electrical, and thermal characteristics.
