Copper dendrites have been prepared by a sonoelectrochemical process from an aqueous solution of Cu 2+ in the presence of polyvinyl alcohol. A SEM image of the morpholohy of the copper formed on the electrode after one electric pulse is presented. A subsequent sonic pulse removes the copper from the electrode surface, cleaning it for the next step. The formation of the dendrites is accounted for by the “drying‐mediated self‐assembly of nanoparticles” theory.
