Influence of solvents on low-temperature reduction-exfoliation of graphene oxide

Graphene due to its extraordinary properties and a wide range of potential applications, has aroused a great interest. Although there are many ways to obtain graphene, the existing methods still possess certain disadvantages. Numerous attempts are made to scale up a new and efficient production method of this material on an industrial scale. A very popular method to obtain graphene is a two-step process. It is based on the oxidation of graphite and subsequent reduction to graphene. This article presents a new way of low-temperature reduction of graphene oxide (GO) in presence of various solvents. Indeed, using of appropriate organic solvents in a particular stage of graphene preparation affects the reduction process and the exfoliation of graphene oxide. The possibility to reduce GO in the presence of a disperser opens new paths for the preparation of graphene containing composites.
