Abstract
The present investigation reports the successful incorporation of Graphite into the PPy matrix via a chemical in-situ polymerization technique. Obtained composites were thoroughly studied by using powder X-ray diffraction (PXRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The corrosion inhibition response of the composites on mild steel (MS), treated in acid media was analysed through atomic absorption spectroscopy (AAS), impedance, Tafel diagram (potentiodynamic polarization) and scanning electron microscopy (SEM) techniques. The results have revealed better inhibitory properties of these composites in the premeditated acid media. The Tafel and impedance curves revealed the dependency of polymer compounds on the corrosion protection of MS steel. The surface of MS is examined through the SEM technique (before and after corrosion). The synthesized materials were further studied for supercapacitor applications using electrochemical Cyclic Voltammetry (CV) and Galvanostatic Charging and Discharging studies (GCD) measurements. The supercapacitor and corrosion properties can be further optimized to develop effective PPy/G structures.
