One of the important questions about understanding the principle mechanisms of electrophoretic deposition in nonpolar systems is to identify the origin of electric charge carried by nanoparticles. We developed a simple model of nanoparticle charging and we explained how the amount of the charge carried by nanoparticles can affect the quality of deposited monolayers. We used the centrifugation of Pt nanoparticles in water-AOT-isooctane reverse micellar system for controlling the charge carried by Pt nanoparticles.
