Execution of Poly Coatings and Corrosion of Copper

Abstract

The erosion defensive poly(aniline-co-o-toluidine) (PAOT) coatings were integrated on copper (Cu) by the electrochemical copolymerization of aniline with o-toluidine under cyclic voltammetry conditions. Fluid oxalate arrangements were utilized as the supporting electrolytes for the amalgamation of PAOT coatings on Cu. The FTIR and 1H NMR spectroscopy examines uncover that the copolymerization of aniline and o-toluidine happens on Cu substrates from a fluid oxalate arrangements and bringing about PAOT copolymer, there are more o-toluidine units than aniline units. The consumption insurance execution of PAOT coatings on Cu was researched in fluid 3% NaCl arrangements by a potentiodynamic polarization procedure. The consequences of the potentiodynamic polarization estimations demonstrated that the PAOT coatings gave more viable consumption assurance to Cu than the individual homopolymers. The consumption rate relied on upon the encourage proportion of o-toluidine utilized for the combination of the copolymer coatings.
