Abstract:
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.
