Artificial sweetener (saccharine) as electrical properties promoter for graphene oxide and graphene

Two novel carbon nanostructures; graphene oxide- (GO) and graphene- (G) functionalized saccharine were synthesized and characterized with a view to study the electrical properties of GO and G in the presence and absence of saccharine. Saccharine was mainly covalently linked to graphene oxide nanostructure with formation of amide bond to afford 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, XRD, AFM and SEM. Herein, saccharine not only used for enhancing the electrical properties of GO or G but it was played a main role in the increasing of the distance between graphene and graphene oxide 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 of LCR showed that the saccharine is able to increase the electrical conductivity of graphene oxide and is made graphene able for rapid charging and lowest loss speed.
