“…The polyelectrolyte characteristic of the polymer is also useful for sensor application. Ppy fulfills above requirements together with having the characteristics of easy oxidation and high chemical stability [10][11][12][13][14][15]. Ppy molecular configuration is responsible for increase in electrical conductivity.…”

Polyvinyl alcohol- polypyrrole (PVA-PPy) nanocomposites with metal chlorides (FeCl3, NiCl2, CuCl2 and ZnCl2) have been synthesized by chemical oxidative polymerization method. These synthesized nanocomposites are characterized by using FTIR, X-ray diffraction, Transition electron microscope (TEM) and Conductivity measurement. TEM exhibit that all of the composites have uniform sizes and morphologies. The diameter of PVA/PPy nanocompsite is 58nm when the metals added to the PVA/PPy the diameters becomes smaller. The variation of electrical conductivity (log ?) with 1000/T for PVA/PPy nanocomposite with metal chlorides revealed that the increase in conductivity s at temperature (393K) with added metals can be attributed to the creation of induced charge carriers in PVA/PPy matrix

“…22 Due to these properties polypyrrole and polyaniline and its derivatives are most extensively studied conducting polymers. [22][23][24][25][26][27][28][29][30][31][32][33] Ozyilmaz et al studied comparative study of passivation of ZnFe and ZnFeCo alloy platings on carbon steel from oxalate and tartrate medium and the results were showing that in oxalate medium passivation exhibited better physical barrier behavior. 34 The purpose of the present study was to synthesize electrochemically PNMP film on thin zinc-nickel (ZnNi) plated carbon steel in sodium oxalate (NaOX) solution.…”

In this study, zinc-nickel (ZnNi) particles were electrochemically deposited on carbon steel (CS) electrode applying constant current of 1 mA with chronopotentiometry technique. Poly(N-methylpyrrole) (PNMP) film on CS/ZnNi electrode was synthesized with cyclic voltammetry technique from 0.10 M N-methylpyrrole containing 0.20 M sodium oxalate solution. The corrosion performances of coated and uncoated electrodes in 3.5% NaCl solution were evaluated with the help of AC impedance spectroscopy (EIS) and anodic polarisation curves. Scanning electron microscopy (SEM) and linear sweep voltammetry (LSV) were used to characterization of coatings. It was shown that the ZnNi particles exhibited important barrier effect on CS substrate. The highest 298350 ohm value of polarization resistance showed that PNMP film on the CS/ZnNi electrode exhibited an effective barrier property and electrocatalytic behaviour protection of substrate for longer exposure time.
