Abstract

According to the classic literature texts on EPD, the net movement of the particles under applying electric field is cited to be zero. What is the response of the suspended particles in different media under applying different AC electric fields and what will be the effects on deposition in practice? What are the parameters affecting on the phenomena? What will be the possible applied innovations? And many other related questions? Part of my research activity and interest is on trying to study and experience for finding answers and addressing the related questions in this regard specially in adjacent for the borders of DC and AC electric fields, by using low AC frequencies at low and high voltages. In these circumstances, dielectrophoresis, liquid motion, and electroosmosis effects can also alter the expectations. Although the emphasis in our job is on manipulating the experimental activities theoretical modeling are also welcomed, and simulations can offer and exploit trustable ideas for better understanding of the mechanisms. Effect of impurities and different materials added on both AC and DC electrophoretic deposition conditions can also be a necessary tool in these studies.
