Investigation of the dielectric properties of TiO2 nanofluids

Nanofluids are tailored suspensions of nanoparticles in a selected base fluid. Nanofluids provide advantages including high thermal conductivity, electrical conductivity and optical absorption compared to the base fluid by itself, even for only a small volume fraction of nanoparticles. The choice of the nanoparticles and base fluid is a challenge in order to achieve maximum absorption. In this work, a method is suggested for selecting the best base fluid for TiO2 nanoparticles to yield the best nanofluid based on the Maxwell-Garnett (MG) effective medium approach.
