Electric permittivity and conductivity of nanofluids consisting of 15Â nm particles of alumina in base Milli-Q and Milli-Ro water at different temperatures

- Opposite effects of temperature and concentration on the nanofluid permittivity.
- Permittivity and electrical conductivity are enhanced with respect to the base fluid.
- Patterns for permittivity and thermal conductivity enhancements are similar.
- Conductivity enhancements are larger in the purer base water.
