Conjugated organic polymers have been studied extensively over the past few decades. This is partly due to their numerous potential applications. The Corrosion Group at North Dakota State University is presently investigating the use of polythiophenes as potential replacements for the currently used chromate system applied to oxidizable metals. The necessity for this replacement is due to the environmental concerns and adverse health effects surrounding the use of chromates.

While a variety of sidechain-functionalized polythiophenes have been investigated, polyalkylaminothiophenes are completely unstudied and could potentially exhibit enhanced properties necessary for anticorrosion applications. Electropolymerization studies of N-alkyl-3-aminothiophenes and N,N-dialkyl-3-aminothiophenes will be presented along with the full characterization of the resulting polymers.
