Graphene Oxide and Graphene functionalized artificial sweetener (Saccharine): Novel Syntheses, Characterization and Comparative study of their electrical properties

Abstract

Two carbon nanostructures; graphene oxide (GO) and graphene (G) were synthesized and characterized with a view to study their electrical properties after functionalization with saccharine. After preparation acyl chloride of graphene oxide, saccharine was mainly covalently linked to graphene oxide nanostructure with formation of amide bond afforded GO-Sac, while it was physically linked to graphene nanosheets with formation of G-Sac. These two saccharine nano derivatives were characterized using FT-IR, powder X-ray diffraction (XRD) and atomic force microscope (AFM) techniques. Herein, saccharine not only used for enhance the electrical properties of GO or G but it was played a main role in increasing of the distance between graphene (G) and graphene oxide (GO) sheets, and consequently prevent the agglomeration effect on graphene oxide and graphene sheets. The electrical properties of these materials were measured using inductance, capacitance, and resistance measurements (LCR). The results showed increased electrical properties of both two carbon nanostructures with enhance their electrical storage after treating with saccharine.
