Investigation of the influence of anodizing modes of copper oxide films on their morphology

Abstract

This work presents experimental data on the surface morphology of Cu2O films obtained by single-stage electrochemical anodization. The process was carried out at a constant applied potential of 50V and at a temperature of 13°C (90 seconds) in an electrolyte based on phosphoric acid. During the experimental work, the optimal synthesis parameters were determined. The morphology of copper porous films was studied using atomic force microscopy Ntegra Therma. The effect of the main anodizing parameters on the morphology of the nanoporous Cu2O film was investigated. According to the results of experimental work, it was found that, epending on the parameters of the anodizing process, it is possible to vary the pore diameter of copper oxide from several tens of nanometers to hundreds of microns, while it is also possible to change the film thickness.
