Abstract—The effect of the conditions of galvanostatic anodizing of copper foil at fiber–glass plastic on
growth kinetic parameters of Cu₂O films is studied. It is shown that the anodic treatment current density in the
sulfate–chloride electrolyte features a logarithmic dependence on the electric field strength in the anodic Cu₂O
film, which is probably caused by the presence of either a pn-transition, or an inversion layer of electronic
conductivity at the Cu/Cu₂O interface. It is found that the dependence of the film thickness on the formation
time at different current densities is nonlinear.

Key words: anodic oxidation, film, kinetics, Cu₂O
