Abstract

Influences of the concentration of additive PEG and overpotential on the Nuclei population density of copper electrocrystallization on a glass carbon electrode (GCE) have been studied in this file. We characterized the experimental data extracted from Li’s work [10] with the least square method and exponential curves. The relationship of nucleation number density and overpotential follows the exponential function basically has been obtained by carrying on the data fitting to experimental data. And with a given overpotential, when inject PEG into acidic cupric sulphate electrolyte with a lower concentration, nucleation number density is reduced, but when the injection concentration of PEG is high enough, nucleation number density is increased instead. While with a certain concentration of PEG, as the overpotential more negative, the nuclei population density increased gradually, but if the injection concentration is low, the change of the growth rate of nucleation number density is not significant.
