Abstract
The nanocomposites of inorganic oxide with conducting polymer display novel properties resulting from the molecular level interaction of the two dissimilar chemical components. Recently, Farah et al have synthesized ZnO–polyaniline (PANI) nanocomposite, and have studied the electronic properties of ZnO-PANI films [1]. Although to date, chromium has proved the best candidate in corrosion inhibition in acidic medium, but still it is hoped that the combination of different techniques and various compounds will provide the required protection against corrosion. Our present study has shown that the ZnO-PANI nanocomposite coatings on steel and aluminum prevents corrosion due to the internal sacrificial electrode formation and as well as the barrier effect at the ZnO-PANI and metal interface.
