Abstract

Electrical conductivity and anticorrision properties are two significant characteristics that were studied on fabricated PAni-Zno composites. The PAni-Zno composites were fabricated by adding nanostructured zinc oxide powder during the polymerization of aniline via in-situ chemical oxidative polymerization. Four different concentrations of PAni-Zno composites. XRD patterns showed that the Zno particles are present in the composite after polymerization. Bulk samples of the PAni-Zno composites reveal that as the amount of zinc oxide in the concentration increases, the electrical conductivity decreases except when the molar ratio of PAni-Zno is 1:1. The decrease implies that the electrical conductivity of the composites is predominantly due to PAni. Change in conductivity is attributed to the addition of relatively less conductive Zno, change in the doping state of the polymer, and the physical interaction of PAni and Zno particles. The iron coated with 1:2 molar ratio of PAni-Zno composites showed the lowest rate of corrosion. The change in the corrosion rate is attributed to the change in the tortuosity of the particles in the composites.
