This is - after earlier patent applications - the first scientific communication describing the new effect of "passivation of metals by PAni". Corrosion potential and corrosion current measurements are shown for various metals with and without PAni coating, and also the dependance of the potential shift from the PAni coating thickness is documented. Previous observations by other research groups and also by us had failed to understand the occurence and mechanism of passivation, and also had failed to develop reproducible procedures and results.
This first systematic evaluation - performed with PAni coatings from dispersion - has lead to further scientific studies in our lab* and together with the Materials Science Institute of the University of Arlington, Texas (USA), Prof. R. Elsenbaumer**. It also started the development of PAni containing lacquer systems suitable as primers.
