Copper oxide thin film is synthesized on the copper substrate at room
temperature by using the anodization technique. The Cu-substrate is placed
in the NaOH solution and the distance between the electrodes is kept
constant though out the experiment. Anodization duration is kept change in a
constant and rhythmic manner to study the time effect on the anodization of
Cu, while the others parameters like voltage, temperature etc. are kept
constant during the experimental procedure. The Crystallographic study of
the synthesized thin films was analyzed by using X-ray diffraction and the
surface morphology of the substrate surface was examined by scanning
electron microscope. The XRD analysis show that the formation of various
phases of copper oxide CuO, Cu2O and Cu4O3. The SEM results also
confirm that the anodization time affects the surface morphology on the
substrate surface.
