CONDUCTOMETRIC PROPERTIES OF ALCOHOLIC NANOSUSPENSIONS OF METAL OXIDES
Journal Title: Физика аэродисперсных систем - Year 2016, Vol 0, Issue 53
Abstract
In this work, we present the experimental study of nanofluids’ electrophysical characteristics concentration dependencies specific behavior (nanoparticles of Al2O3, ZnO and Fe2O3 in isopropyl alcohol) at low concentrations. The values of a conductivity, electrical capacitance and dielectric permittivity are measured depending on the suspended particles’ concentration for low concentrated nanofluids far from the percolation threshold and for different periods after their preparation. It is shown that the increase of the electrophysical parameters with increasing concentration of the pointed nanoparticles (which themselves are non-conductive) may be explained by a formation of an electrical double layer around the particles and a percolation of particle clusters.
