Synthesis and Ultrasonic Investigation of Reduced Graphene Oxide Nanosuspension with Water

Abstract

Synthesis of Graphene Oxide (GO) was done using Original Hummer's Method. The prepared GO specimen was reduced further with Hydrazine monohydrate to create Reduced Graphene Oxide (RGO). RGO were evaluated using characterization techniques such as FESEM, EDS, FTIR, XRD, and Raman. These techniques help to confirm the production of GO and conversion of GO into RGO. Suspension of RGO in double-distilled Water with different concentrations was produced using ultrasonication for 24 hours. This suspension was further tested with the help of the UV-Vis technique to confirm the presence of RGO in the suspension. DLS was done to confirm the nano dimensions of RGO particles in the water solution. Ultrasonic velocity, density, and viscosity were measured for all prepared nanosuspensions. The acoustical parameter such as adiabatic compressibility, intermolecular length, and acoustical impedance was calculated from experimental data.
