Deposition of ceramic Nanoparticles in Low Frequency AC Electric Field: Modeling and Experiment

In this work, we have investigated particle movement in symmetric AC electric field to understand how particles deposit in an oscillatory electric field. A mathematical model was developed to find nanoparticle trajectory in liquid medium. The competition between electrical, Brownian and hydrodynamic forces was studied by model. According to modelling and experimental observations, we have shown that electric forces can force ceramic nanoparticles to deposit on electrode surface despite disturbing forces such as Brownian and hydrodynamic which are exerted on the particle in electric field.
