Anisotropic copper micro- and nanoparticles synthesis and characterization, either in suspension or localized on a surface, are current areas of growing interest due to its potential use in many applications ranging from catalysis, microelectronics, biosensors and solar cells. In this work, the electrochemical deposition of copper at varying overpotentials and in presence of surfactants is studied. Cyclic voltammetry is used to identify and characterize the different overpotential regimes for copper deposition in the presence of surfactants. The effect of surfactants with different head groups (Cationic, anionic and non-ionic) and varying hydrocarbon chain lengths on the anisotropy of electrodeposited copper particles is studied.
