Electropolymerization of 2-aminophenol - Electrochemical and spectroscopicstudies

The anodic oxidation and electropolymerization of 2-aminophenol on platinum , vitreous carbon and copper electrodes has been studied in alkaline hydroa lcoholic medium using electrochemical techniques (cyclic voltammetry and ch ronoamperometry). This oxidation leads to the formation of homogeneous and adherent films, insoluble in usual solvents that can be of a great interest in the domain of materials protection. The analysis by ESCA and IR spectro metry has permitted the identification of the organic film and allows to pr opose a mechanism for 2-aminophenol electropolymerization.
