An investigation on the long-term stability of TiO2 nanofluid

TiO2 nanofluid is a noble product of nanotechnology due to its high stability and better suspension property. The main objective of this article is to highlight some important factors that control the electrokinetic property as well as the stability of TiO2 nanofluid. Zeta potential, pH-factor and surfactant (Hexasodium Salt (NaPO3)(6)) are found to control or modify the suspension property of TiO2 nanofluid. The suspension property strongly controls the electrokinetic property in order to minimize the coagulation or agglomeration of nanoparticle in the base fluid. (C) 2019 Elsevier Ltd.
