Synthesis and Study of a Polypyrrole-Aluminum Oxide Nanocomposite Film on an Aluminum Surface

摘要

Using the method of electrochemical anodization, aluminum oxide porous films are obtained in a sulfuric acid solution. The morphology of the aluminum oxide surface is studied by the method of scanning electron microscopy. The high-quality elemental analysis of the initial and oxidized Al films is performed using the method of electron microprobe analysis. A protective composite polypyrrole-aluminum oxide film is produced on the aluminum surface on top of a porous aluminum oxide film in the galvanostatic oxidation mode by the electrochemical synthesis method. The properties of the polypyrrole-aluminum oxide composite film are studied by the methods of voltammetry, as well as impedance and FTIR spectroscopy.
