Preparation by Ultrasonic Treatment of Graphene Oxide

Oh et al. (2010) have shown a preparation route using ultrasonic irradiation to produce graphene oxide (GO) layers. Therefore, they suspended twenty-five milligrams of graphene oxide powder in 200 ml of de-ionized water. By stirring, they obtained an inhomogeneous brown suspension. The resulting suspensions were sonicated (ultrasonically treated graphene oxide was produced 30 min, 1.3 × 105J), and graphene oxide was produced. An FTIR spectroscopy showed that the ultrasonic treatment did not change the functional groups of graphene oxide. Xu and Suslick (2011) describe a convenient one-step method for preparing polystyrene functionalized graphite. Their study used graphite flakes and styrene as basic raw materials.

By sonicating the graphite flakes in styrene (a reactive monomer), the ultrasound irradiation resulted in the mechanochemical exfoliation of graphite flakes into single-layer and few-layer graphene sheets. Simultaneously, the functionalization of the graphene sheets with the polystyrene chains has been achieved.
