Accoustical and Thermodynamical Study of Graphene Oxide- N-Methyl-2-Pyrrolidone Nanosuspension

Graphene Oxide (GO) shows some excellent properties like very high electron mobility, excellent thermal conductivity, and most robust material, etc. All these properties make the GO a unique material. GO was produced in this study with the help of Hummer's method. This prepared GO was used to create a nanosuspension with N-Methyl-2-Pyrrolidone (NMP). NMP is an excellent solvent which extensively used in industry to dissolve many polymers. Another use of the NMP is in the paint industry; pharmacy industries use NMP in both oral and transdermal delivery routes. Here in this study, we use NMP as a base fluid for the suspension of GO nanoparticles with the help of an excellent ultrasonication technique. DLS checks the stability of the prepared nanosuspension. This prepared nanosuspension used to study various thermoacoustic parameters. The interferometer has calculated the velocity of the samples; the pycnometer estimated the density of the GO-NMP nanosuspension, and the rotational viscometer used to calculate the viscosity of the nanosuspension. All these studies are carried out at the temperature range from 298 to 313 K. These experimental values used to calculate the derived costs like adiabatic compressibility, attenuation, relaxation time, Bulk modulus, etc. in this paper; we have calculated the various acoustical properties of the GO-NMP nanosuspension.
