Product Details

Graphene is an atomic-scale honeycomb lattice made of carbon atoms. It is the world's first 2D material and is one million times smaller than the diameter of a single human hair. However, it is many times stronger than steel, yet incredibly lightweight and flexible. It is electrically and thermally conductive but also transparent. As a single layer graphite, graphene has raised great interest due to its potential applications in different fields of material science for developing nanocomposites, sensors, supercapacitors, hydrogen storage, photonics and optoelectronic devices.

The oxidation of graphite produces graphite oxide (GO) which has hydrophilic functional groups (-OH, epoxide, -COOH). Those groups promote the intercalation of water molecules into the gallery and the graphene sheets can be easily detached from each other by sonication, thus producing highly dispersible GO sheets in aqueous medium. These exfoliated GO sheets are usually used for different applications or are further functionalized to use for targeted applications. For example, the GO is electrically insulating but becomes conducting when it is reduced to produce reduced graphene oxide (rGO) by sodium borohydride or hydrazine hydrate.

Since its first discovery in 2004, graphene has been set to improve the quality of life for many across the globe. From inexpensive water purification systems to greener, more efficient cars and planes; From flexible phones, solar cells to biomedical applications. To advance the graphene research and promote the commercialization of graphene technologies, Matexcel offers a number of graphene derivatives as well as customized synthesized graphene products, including mono/multilayer graphene oxide, functionalized graphene oxide.
