Interpretive Summary:

Technical Abstract: Plating, painting and the application of enamel are the most common anti-corrosion treatments. They are effective by providing a barrier of corrosion resistant material between the damaging environment and the structural material. Coatings start failing rapidly if scratched or damaged because a corrosion process called “pitting” occurs at very high rates in small cracks or paint defects. Thin polymer films are the subject of intensive study as cheap and efficient alternatives to traditional coating technology. They are easy to tailor to the specific needs of an application, have varying diffusive and hydrophobic properties and are easily applied, usually by spraying or dipping in solutions. Experiments investigated the corrosion inhibitive properties of 29 polysaccharide films denominated by a code name representing a culture batch number. Polarization curves along with impedence spectroscopy suggest that the polymer films studied act as anodic type corrosion inhibitor.
