graphene oxide

Graphene oxide (GO) is an oxidized form of graphene, synthesized through the oxidation and exfoliation of graphite. GO shares the same thin structure as graphene, but includes intercalated oxygen-containing functional groups. The properties and applications of GO depend on the degree of oxidation. In general, GO shows several characteristics:

• Unlike graphene, it is hydrophilic (highly dispersible in water and other organic solvents to form stable aqueous colloids).
• As graphene, it has a high surface area.
• It is suitable to be used in composites as it can easily be mixed with polymers and other materials.
• It can be deposited on almost any substrate.
• It is an electrical insulator (it lacks graphene´s conductivity).
• It is fluorescent.
• It can be reduced to make lower cost/higher volumen Graphene.

GO can be functionalized for multiple applications, such as optical devices, biomedical sensors, electronic devices, energy generation/storage, corrosion resistant coatings, drug delivery and solar cells.
