N2 - Microrheology of several nanofluids based on water, ethylene glycol, and isopropyl alcohol with single-wall and multiwall nanotubes has been studied by diffusion wave spectroscopy. Their viscosity and rheology have preliminarily been investigated, and it is shown that, beginning with a certain carbon-tube concentration, nanofluids become non-Newtonian and viscoplastic. At the same time, it has been experimentally established that these nanofluids are viscoelastic. Various viscoelastic characteristics of these nanofluids have systematically been analyzed and compared.
