Abstract
Effect of polyethylene glycol (PEG; m.w. 3000) on the Cuad deposition at smooth platinum in 0.5 M H2SO4 + 0.1 M CuSO4 solutions and on the initial copper electrocrystallization stages is studied. According to cyclic voltammetry, PEG barely affects the Cuad formation kinetics. Adding PEG hampers dissolution of deposited copper. As follows from chronoamperograms, PEG makes no impact on the nucleation character (progressing nucleation) but hampers the copper nucleation process.
