Assembly of two-dimensional ordered monolayers of nanoparticles by electrophoretic deposition

In this article the effect of field strength, temperature and square-wave p ulse on the deposition structure of gold nanoparticles is investigated and 2D structures of silver and two kinds of rare-earth carbonate particles are synthesized by electrophoretic deposition (EPD). The results indicate that EPD is a general phenomenon that occurs on the electrode/sol interface and that the EPD method may be developed for the assembling of 2D structures o f nanoparticles. On the other hand, the results also show that the composit ion and surface condition as well as the size distribution of the particles can affect the order of the particles in the monolayer.
