SCIENTIFIC ENGINEERING OF ANTI-CORROSION COATING SYSTEMS BASED ON ORGANIC METALS (POLYANILINE)

摘要

In 1985 David DeBerry found that polyaniline, electro-deposited on passivated steel in strong acid environment, was enhancing the corrosion protection of this metal. No further research was done to find out what mechanism was reducing the corrosion rate and if polyaniline deposited by other than electrochemical means on non-prepassivated metal surfaces would lead to any kind of corrosion protection, until our laboratory had developed first polyaniline containing paints and published first corrosion inhibition by such paints in 1988 . It took another 5 years to come to reproducible results first by using pure polyaniline coatings from organic dispersions, which were deposited on untreated metals like normal steel, stainless steel and copper.
