Synthesis and Ultrasonic Investigation of Graphene Oxide and Reduced Graphene Oxide Nanosuspension with n, nDimethylformamide

Abstract

Graphene Oxide (GO) shows remarkable properties in many filed like electronics, sensors, biomedical, thermal conductivity, nanofluids, etc. In this paper, to manufacture GO the original hummer's method was employed. To confirm the transformation of carbon into GO, several characterization methodologies including FESEM, FTIR, RAMAN, EDS, and XRD were employed. GO suspension at different concentrations composed with the help of exhaustive ultrasonication suspension of GO in double distilled water. After one week, UV-Vis spectroscopy was used to examine the stability and the DLS technique was used to confirm the presence of GO in the suspension and the nanoparticle size of GO in the suspension. To calculate the acoustical parameter of the prepared samples ultrasonic velocity, density and viscosity were measured with the help of instruments available. Further, these values were employed to compute parameters like adiabatic compressibility, attenuation, acoustical impedance, etc. Acoustical thermal properties of the prepared sample of Water-GO suspension are reported in this paper.
