Hettich UNIVERSAL 320 Benchtop Centrifuge Used in Graphene Functionalization Research
The Hettich UNIVERSAL 320 benchtop centrifuge was used for graphite exfoliation in the study entitled “Functionalization of Graphene via 1,3- Dipolar Cycloaddition,” published in the American Chemical Society (ACS) Nano journal.
The study’s main objectives were to test and observe the reaction of graphene in 1,3-dipolar cycloaddition of azomethineyildes and to discover whether the resulting chemical reaction can open the possibility of manipulating the carbon allotrope for constructing nanomaterials.
Researchers obtained graphene sheets 1 (Product 1) using a solvent extraction procedure, which allowed effective production of single and few graphene layers sans the use of intercalants, polymers or surfactants, all of which may impede natural organic reaction.
After the preparation of Product 1, graphite exfoliation was performed by dispersing the samples in 200mL of N-Methyl-2-pyrrolidone (NMP). The resultant dispersion was then centrifuged using the Hettich UNIVERSAL 320 for 90 minutes at 500 rpm. Researchers performed decantation by pipetting off the dispersion’s top half.
Ultimately, the study determined that exfoliated graphene was successfully functionalized using the 1,3-dipolar cycloaddition of azomethineyildes.
Hettich’s comprehensive line of centrifuges enables scientists to conduct important testing and research, such as this study on graphene functionalization. The Hettich UNIVERSAL 320 is a quiet, safe and reliable benchtop centrifuge that is suited for many applications in clinical, research and industrial laboratories.
