Abstract

Aromatic solutions containing NButylamine salts have sufficient then110chemical stability, wide polarization potential, high boiling point and acceptable dielectric coefficient suitable for electrolytic coating of the active metallic ions. In this study, nucleation/growth kinetics of thin metallic layers precipitated from copper containing N-Butylamine complexes dissolved in naphthalene is investigated via
cyclic voltammetry, chronoamperometry and electrochemical impedance frequency response method. Results indicate _ an instantaneous three-dimensional electrochemical crystallization of copper
concomitant with a diffusion-controlled
growth regime. The diffusion coefficient of copper containing complex and the standard rate constant of the reaction are calculated from the data, which appear to be in the
range of 3-6 x 10-6 cm2/s and 2-6 × 10-3
cm/s., respectively. The relatively small reaction as well as diffusion rates seem to be due to the complexion of copper ions with large aromatic legends.
