Ultrasonic and thermodynamic investigation of reduced graphene oxide-n methyl-2-pyrrolidone nanosuspension

Abstract

Reduced Graphene Oxide (rGO) reveals several remarkable properties resembling excessive electron mobility, superb thermal conductivity, and very strong material, etc. All these properties make up the rGO an outstanding material. GO was made in this research with the support of Hummer’s method and additional reduction is done with the help of Hydrazine Monohydrate. This prepared rGO was utilized to produce a nanosuspension along with N-Methyl-2-Pyrrolidone (NMP). NMP is an admirable solvent which widely utilized in production to dissipate many polymers. Additional use of the NMP is in the paint manufacturing; pharmacy productions which uses NMP in both oral and transdermic delivery methods. In this report, we use NMP as a foundation fluid for the suspension of rGO nanoparticles with the support of a superb ultrasonication method. DLS verifies the stability of the nanosuspension. In this paper prepared nanosuspension is used to study the various thermal and acoustical properties. Velocity, density and viscosity of the nanosuspension has been calculated experimentally and experimental values used to calculate the derived parameters like adiabatic compressibility, attenuation, relaxation time, Bulk modulus, etc.
