Nanofluids are suspensions of nanometrical size particles in a liquid base, which is usually water, oil or ethylene glycol. The potential practical use of nanofluids caused in recent years a considerable intensification of research into their properties. The most widely studied of physical properties include the fluid rheology, thermal conductivity and electrical parameters. The paper presents electrical properties of aluminium oxide (Al₂O₃) nanofluids based on ethylene glycol (EG). Nanoparticles used to produce nanosuspensions employed in measurements have size between 100-300 nm. Electrical properties was investigated in a wide range of temperatures (-10°C-55°C) and frequencies (0.02-200 kHz) using a measuring LCR bridge connected to a temperature stabilization system based on liquid nitrogen and Peltier element.
