Synthesis and Ultrasonic Investigation of Graphene Oxide and Reduced Graphene Oxide Nanosuspension with Ethylene Glycol

Abstract

The Original Hummer’s Method was used to produce Graphene Oxide. Hydrazine monohydrate was used to produce Reduced Graphene Oxide by the Graphene Oxide sample. The processed Reduced Graphene Oxide was confirmed by numerous characterization methodologies: RAMAN, X-ray diffraction, Field emission scanning electron microscopy, Energy-dispersive X-ray spectroscopy, and Fourier transform infrared. The numerous characterization methodologies verified the manufacture of Graphene Oxide and the transformation of Reduced Graphene Oxide from Graphene Oxide. The ultrasonication process of double distilled water was used for 24 hours to produce reduced graphene oxide nanosuspension. Further existence of reduced graphene oxide was confirmed by the ultraviolet-visible spectroscopy operating procedure in the nanosuspension. The dimension of reduced graphene oxide fragments was verified by an Ethylene Glycol solution's dynamic light scattering technique. Viscosity, density, and ultrasonic velocity for every concentration were calculated. Other parameters, such as acoustical impedance, intermolecular length, and adiabatic compressibility, are also calculated from investigated data.
