Hettich Universal 320 Utilized in the Study of Functionalization of Graphene via 1,3-Dipolar Cycloaddition

ACSNano Vol.4 No. 6 recently featured an article entitled “Functionalization of Graphene via 1,3-Dipolar Cycloaddition”. The study discussed a convenient method to evaluate graphite exfoliation in using Hettich's Universal 320 Centrifuge.

In this study, few-layer graphenes (FLG) produced by dispersion and exfoliation of graphite in N-methylpyrrolidone were successfully functionalized using the 1,3-dipolar cycloaddition of azomethine yildes. Exfoliation was achieved by dispersing 24 mg of graphite into 200 mL of NMP and sonicated for 30 minutes in a sonic bath of low power. The resultant dispersion was processed with a Hettich Universal 320 centrifugator for 90 minutes at 500 rpm. With the use of other methods such as spectroscopy and microscopy, "the results identify exfoliated graphene as a considerably more reactive structure than graphite; hence, opening the possibility to control the functionalization of graphene as a scaffold in the construction of organized composite nanomaterials.

Chemical manipulation of graphene and transforming it into different functional structures will enable its maximum functionalization for a great number of applications. One is the development of innovative devices, among others. Hettich manufactures the Universal 320, centrifuge series for Clinical, Research and Industrial applications. This centrifuge provides consistent, reliable and accurate results, spin after spin.
