In this research, the AC electric field deposition behavior of TiO2 ceramic nanoparticles at different applied frequencies was investigated. For this purpose, dilute suspensions of ceramic nanoparticles in acetone media were prepared. The deposition process was conducted on two parallel planar electrodes for a dwell time of 10 minutes. It has been shown by scanning electron microscopy (SEM) that by increasing the frequency from 1 to 10000 Hz, the deposition mechanism of TiO2 particles on the surface of gold electrodes changes. The results obtained from the SEM images also show the capability of this technique for controlling the deposition pattern and manipulating ceramic nanoparticles as it was reported for biological nanoparticles previously.
