Abstract
The agglomeration of nanoparticles during electrocodeposition of nanocomposite thin films is an unresolved issue. In this paper, the effects of ultrasonic irradiation on agglomeration during electrocodeposition of Cu–Al 2O 3 and Cu–CeO 2 nanocomposite thin films on a silicon substrate are investigated. In addition, the effect of electrolyte concentration on agglomeration of nanoparticles is investigated. Irradiation by ultrasound during electrocodeposition yields smaller grain size, improved surface conditions, decreased agglomeration and higher volume fraction of nanosized inert particles within the nanocomposite thin films.
