“…Figure 2cand d shows an SEM image of the PPy-coated GF surface, confirming the formation of PPy film with few cauliflower like morphology constituted by microspherical grains which is well agreement with the previous reports of PPy film deposited by electro-polymerization technique 39,40. The cross sectional SEM image of GF/PPy film shows nearly 5 micron thick film was coated over the lapping film surface (Figure S1f).…”

Flexible supercapacitor electrodes have been fabricated by simple fabrication technique using graphite nanoflakes on polymer lapping films as flexible substrate. An additional thin layer of conducting polymer polypyrrole over the electrode improved the surface conductivity and exhibited excellent electrochemical performances. Such capacitor films showed better energy density and power density with a maximum capacitance value of 37 mF cm(-2) in a half cell configuration using 1 M H2SO4 electrolyte, 23 mF cm(-2) in full cell, and 6 mF cm(-2) as planar cell configuration using poly(vinyl alcohol) (PVA)/phosphoric acid (H3PO4) solid state electrolyte. Moreover, the graphite nanoflakes/polypyrrole over polymer lapping film demonstrated good flexibility and cyclic stability.

“…In addition; this shows that O 2 reduction reaction (cathodic reaction) takes place at the polymer surface. In other words, this confirms the displacement of the electrochemical interface (e.g., from metalelectrolyte interface to polymer electrolyte interface) [42]. Hosseini et al found that polypyrrole/ZnO nanocomposite coating offered excellent barrier property with constant E ocp value [43].…”

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.
