Polymers have been found effective stabilizers of colloidal metal nanoparticles. Recently, polymer nanofluids are the subject of considerable interest because of the unique properties that can be achieved with these materials. At the same time, because of their high surface to volume ratio, nanoparticles suspended polymer matrix significantly are revealing some new properties which are not present in either of the pure materials. Therefore, the investigation of the influence of nanoparticles on the properties of a polymer matrix is necessary in order to be able to better predict the final properties of the complex fluids. In the present work we have made the study of the ultrasonic attenuation and velocity in a polymer colloidal solution with dispersed Cu-metal nanoparticles (nanofluid). We prepared stable nanofluids containing copper metal nanoparticles suspended in the base fluid polyvinyl pyrrolidone (PVP) and measured ultrasonic properties.
