Fig. 7 Effect of temperature on thermal conductivity of ZnO–ethylene glycol nanofluids (Suganthi
et al. 2014)
influences the thermal properties of the nanofluid. pH of a nanofluid affects these
surface charges and this is well defined by Wang and Zhu (2009) in their investigation
of thermal conductivity of Al 2 O 3 and Cu-based nanofluids, which is shown in Fig. 8.
An increase in pH alters the charges on the surface of nanoparticles which raises the
electrostatic forces of repulsion between two nanoparticles. This leads to reduction in
agglomerative tendency of the nanoparticles in the nanofluid. Thus, the pH is found
