Researchers of Shiraz Islamic Azad University have succeeded in reducing Graphene Oxide which can be applied in producing displays.

ANA reports that researchers at Shiraz IAU have presented a green method for reducing graphene oxide to graphene.

One of the advantages of graphene oxide is its easy dispersability in water and other organic solvents, as well as in different matrices, due to the presence of oxygen. This remains as a very important property when mixing the material with ceramic or polymer matrixes in improving their electrical and mechanical properties.

Reduced Graphene Oxide is the most commonly used form of graphene despite structural differences. it has been used in various fields including pharmaceuticals, hydrogen storage, fuel cells, supercapacitors, batteries, solar cells and polymer composites.

Graphene Oxide is used, owing to its conductive properties and ease of preparation, in light panels and computers. Today's graphene is normally produced using mechanical or thermal exfoliation, chemical vapor deposition (CVD), and epitaxial growth. One of the most effective way of synthesized graphene on a large scale could be by chemical reduction of graphene oxide.

In order for graphene oxide to be usable as an intermediary in the creation of monolayer or few-layer graphene sheets, it is important to develop an Redox process that is able to separate individual carbon layers and then isolate them without modifying their structure. So far, while the chemical reduction of graphene oxide is currently seen as the most suitable method of mass production of graphene, it has been difficult for scientists to complete the task of producing graphene sheets of the same quality as mechanical exfoliation, for example, but on a much larger scale. Once this issue is overcome, graphene will probably become much more widely used in commercial and industrial applications.
