“…As a result, the introduction of ZnO nanoparticles into to PoPd coatings led to exhibiting high corrosion protection properties. Similar result was obtained by Chen et al, in which they found that the insertion of ZnO nanoparticles improved the corrosion properties of polypyrrole [23]. It can be concluded that both electrochemical protection and barrier effects cause the corrosion protection of the composite coatings.…”

“…The film capacitance of PoPd/ZnO nanocomposite coating was found to be higher than that of pure PoPd. The results showed that PoPd/ZnO nanocomposite coating had better conductivity and charge storage capability [23]. Other authors reported the effect of the nanosize additives to improve the anticorrosion electrochemical barrier layer properties of polymers for diffusion of solvent [40][41][42][43].…”

“…Mahmoudian et al studied the effect of the addition of ZnO nanoparticles in electropolymerization of poly(N-methyl pyrrole ) on steel substrates from oxalic acid [22]. Chen et al found that the PPy/ZnO nanocomposites coating had relatively better charge-carrying capacity, better conductivity, and higher corrosion protection properties than that of pure PPy [23]. PPy/ZnO composites film could be also synthesized by using electropolymerization method and the composite film exhibited an improved xanthine biosensing [20].…”

Poly(o-phenylenediamine) and poly(o-phenylenediamine)/ZnO (PoPd/ZnO) nanocomposites coating were prepared on type-304 austenitic stainless steel (SS) using H2SO4acid as electrolyte by potentiostatic methods. Fourier transforms infrared spectroscopy and scanning electron microscopy techniques were used to characterize the composition and structure of PoPd/ZnO nanocomposites. The corrosion protection of polymer coatings ability was studied byEocp-time measurement, anodic and cathodic potentiodynamic polarization and impedance techniques in 3.5% NaCl as corrosive solution. It was found that ZnO nanoparticles improve the barrier and electrochemical anticorrosive properties of poly(o-phenylenediamine).

“…Increase in corrosion current and decrease in protection efficiency corroborates with a decrease in R p value for PVKZ-3 coatings. Similar results were obtained by Chen et al, in which they found that the insertion of ZnO nanoparticles improved the corrosion properties of polypyrrole [47]. The coating porosity is one of the important parameters, which strongly governs the anticorrosive behavior of the coatings [48,49].…”

A novel nanocomposite coating containing poly (N -vinyl carbazole) (PVK) and zirconia (ZrO2) nanoparticles was synthesized using chronoamperometry. The effect of ZrO2 nano particles into the PVK matrix and its mechanical, corrosion protection ability on 316L SS substrates were studied. The incorporation of the nanoparticles was endorsed by attenuated total reflectance infrared spectroscopy (ATR-IR) and EDAX analysis. The spheroidal morphology and core-shell structure were revealed with scanning electron microscopy (SEM) and transmission electron microscopy (TEM) techniques. The thermal studies exhibited the stability of coating. The anticorrosion performance of PVK-ZrO2 nanocomposite coatings in 3.5 weight (wt.)% NaCl medium was performed with potentiodynamic polarization technique and electrochemical impedance spectroscopy (EIS) studies. The corrosion rate of PVK-ZrO2 nanocomposite coated 316L SS was found to be 0.58 times lower than uncoated 316L SS and a significant decrease in corrosion potential was realized from −0.211 VSCE for uncoated 316L SS to 0.112 VSCE for PVK-ZrO2 nanocomposite coated 316L SS substrates. The results of this study clearly ascertain that the PVK-ZrO2 nanocomposite has an outstanding potential to protect 316L SS against corrosion in a 3.5 wt.% NaCl environment.

In the present work, PPy, ZnO, and polypyrrole/zinc oxide (PPy/ZnO) microcomposites (1, 2, and 5 wt%) were prepared and their properties have been tuned for anticorrosion applications on low carbon mild steel. The synthesized products: ZnO, PPy, and composites were characterized by various sophisticated analytical techniques such as XRD, FTIR, Raman, FESEM, EDX, UV–VIS, TGA, and BET. The band frequencies observed at 480 and 588 cm−1 in FTIR spectrum correspond to stretching vibrations of Zn‐O and N‐H bonds, respectively, broadening of the bands in the composites indicate strong interactions between ZnO and PPy matrix. The potentiodynamic polarization study of PPy and PPy/ZnO composite was carried out in 3.5% NaCl solution to investigate the corrosion resistance efficiency. PPy/1 wt% ZnO (Icorr = 190 nA) composite coating on low carbon mild steel was observed to exhibit best corrosion protection property compared to PPy (121 μA), 2 and 5 wt% ZnO (242, 295 nA) composites. © 2019 Wiley Periodicals, Inc.
