Corrosion protection of copper by polyaminophenol films

Poly(o-aminophenol) with two redox processes: A spectroelectrochemical study

“…Although literature is also available on electrochemical and spectroelectrochemical studies of the m-and p-isomers [6,7] o-aminophenol (OAP) has attracted most attention because of the formation of an electroactive polymer during its chemical and electrochemical oxidation [8][9][10][11]. Poly(o-aminophenol) (POAP) has been investigated with electrochemical, spectroelectrochemical, ellipsometry and impedance measurements [12][13][14][15][16] and applied in biosensors and corrosion protection [17,18]. Presently it is agreed that POAP is a ladder polymer composed of phenoxazine-type units.…”

The electrochemical synthesis of polypyrrole at a copper electrode: corrosion protection properties

“…For example, Cicileo et al [5] have shown that oxime compounds, such as benzoinoxime and salycilaldoxime lead to the formation of a polymeric Cu(II) Á/ inhibitor complex that exhibits strong corrosion inhibition. Guenbour et al [6] have studied the corrosion protection of copper by polyaminophenol films obtained through the electropolymerization of the monomer, 2-aminophenol, in alkaline hydroalcoholic solution. There have also been reports on the formation of polymeric films through the electrochemical oxidation of 3-amino 1,2,4-triazole [7,8], self assembled monolayers of alkanethiol [9,10], alkanethiol monolayers modified with tetrachlorosilane, 1,2-bis(trichlorosilyl)ethane, 1,8-octanediol, and/or octyltrichlorosilane [11] and insulating polymers fabricated by oxidizing 2-mercaptobenzimidazole in alkaline water Á/methanol solutions [12].…”

Application of Polytyramine Nanoparticles to the Corrosion Protection of Copper

“…9,10 Electropolymerization is a method of synthesis and deposit of thin layers of polymers on commercial metals. For this reason, pyrrole, 2 thiophene, aniline, 4,11,12 aminophenol, 13 and their derivatives and other monomers were used for corrosion protection of metals. Since dissolution of oxidizable metals, like copper, occurs at lower potential than that of monomer oxidation potential, metal must be passivated to generate a suitable surface prior to the electropolymerization of electroactive specimens.…”
