Abstract

This study examines the use of spin-applied conjugated polymers such as polyanilines for corrosion and dissolution protection of silver and copper. In particular, attention is given to the protection that these polymers provide under conditions of an applied potential and at elevated temperature. These particular conditions are those in which current inhibitors such as benzotriazole do not provide acceptable protection for the metal. A number of polyaniline derivatives are studied, including the unsubstituted parent polymer and the substituted poly-o-phenetidine both nondoped and doped, with several different protonic acids. The polymers are readily soluble in organic solvents and can be applied as thin coatings onto the metal surface. The corrosion protection of the resulting structure is determined by electrochemical and inductively coupled plasma techniques using water as an electrolyte and under varied conditions in which the material is processed and doped. The poly-o-phenetidine is found to adhere well to the metal surface and provides exceptional protection both under an applied potential and at elevated temperature.

Corrosion prevention capability of polyaniline (emeraldine base and salt): An XPS study

Conference Jasty, S; Epstein, A

There has been a keen interest in the use of polyaniline coatings for the corrosion protection of Fe and its alloys. To date, the primary focus has been on the doped form of the emeraldine oxidation state; also, the polyaniline has been applied, electrochemically or chemically, as an overcoat on the metal. In the present study, the surface sensitive XPS technique has been applied to investigate (1) the effectiveness of the neutral emeraldine base as well as the doped emeraldine hydrochloride forms of polyaniline in corrosion inhibition and (2) the ability of a polyaniline undercoat in providing corrosion protection bymore »« less
Polyaniline/poly acid acrylic thin film composites: a new gamma radiation detector

Journal Article Lima Pacheco, Ana; Araujo, Elmo; Azevedo, Walter - Materials Characterization

In this paper, we present a new and straightforward route to prepare polyaniline/poly acid acrylic (PAA) thin film composites in large areas and on almost any surface. This method was developed to improve the mechanical and adherence properties of polyaniline devices used as ionization radiation sensors. The route consists of the combination of the metal oxidant with polymer acid to form a highly homogeneous and viscous paste, which can be easily spread over any surface. In the second step, an aniline acid solution is brought in contact with the dried paste where polymerization occurs, yielding a high homogeneous and conductingmore »« less

Interactions between polyaniline and silver cations

Journal Article Zhang, A; Cui, C; Lee, J; ... - Journal of the Electrochemical Society

Polyaniline (PAn) is one of the more illustrious conductive polymers with demonstrated successes in such diverse application areas as rechargeable batteries, electrochromic windows, electrocatalysis, anticorrosion coatings, and inorganic and biological sensors. Polyaniline (PAn) thin films were prepared from aniline solutions in H{sub 2}SO{sub 4} by scanning the potential cyclically between {minus}0.2 and 0.8 V (vs. SCE). Films of different thicknesses, and hence different intrinsic oxidation states, reacted differently with 0.1M AgNO{sub 3}. While redox reactions leading to the deposition of silver metal occurred between Ag{sup +} and PAn in thick films ({>=} 40 deposition cycles), thin films ({<=} 20 depositionmore »« less

Electrochemical studies of corrosion inhibiting effect of polyaniline coatings

Conference Wei, Yen; Wang, Jianguo; Jia, Xinru

A series of electrochemical measurements, including corrosion potential (E{sub corr}), corrosion current (i{sub corr}), Tafel`s constants and polarization resistance (R{sub p}), have been made on polyaniline-coated cold rolled steel specimen under various conditions. Both the base and acid-doped forms of polyaniline were studied. The base form of polyaniline was found to offer good corrosion protection. This phenomenon may not originate merely from the barrier effect of the coatings, because the nonconjugated polymers such as polystyrene and epoxy did not show the same electrochemical behavior. The polyaniline base with zinc nitrate plus epoxy topcoat appeared to give better overall protection relativemore »« less
Spectroscopic characterization of the photoinduced doping of methyl substituted polyaniline

Conference Benugopal, G; Quan, X; Johnson, G; ...

Poly(o-toluidine), methyl-substituted polyaniline, films have been doped by an acid generated by the irradiation of a non-metallic, non-ionic photoacid generator with UV light. The ultraviolet-visible and infrared spectra of the polymer obtained during photoinduced doping are similar to those obtained after doping with hydrochloric acid indicating that the changes produced in the chemical and electronic structures of the polymer are identical. Under the present conditions, it appears as though the photoinduced doping process is incomplete and hence result in films that are only slightly more conductive than the undoped samples. However, the photodoped samples are insoluble in solvents that dissolvemore »« less
