The title of the article we will review today is:Enhanced anti-corrosion characteristics of epoxy-functionalized graphene oxide nanocomposite coatings on mild steel substrates
Authors and Journal: This research paper was written by P. Sivaranjana, Subramaniyan Ramasundaram, Tae Hwan Oh, Sikiru O. Ismail, Rajini N, and Faruq Mohammad. It was published in the Journal of Materials Research and Technology.
This study explores the development of epoxy-functionalized graphene oxide (FGO) nanocomposite coatings for corrosion protection of mild steel. The authors employed X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM) to analyze the structural and morphological properties of the functionalized graphene oxide. They prepared coatings with varying concentrations of FGO (10-50 ppm) using a dip-coating method to enhance the corrosion resistance of mild steel.
Electrochemical analysis, including electrochemical impedance (EI) and potentiodynamic polarization (PP) studies, demonstrated that the coating significantly improved corrosion resistance, with a maximum inhibition efficiency of 87% at 50 ppm FGO concentration. The authors found that higher concentrations of graphene oxide resulted in better corrosion protection by reducing metal removal and delaying crack propagation.
Key Features of the Research:
- Development of epoxy-functionalized graphene oxide coatings for corrosion protection.
- Characterization of FGO structure and morphology using XRD, SEM, TEM, and Raman spectroscopy.
- Optimization of coating concentration to achieve maximum corrosion resistance.
- Electrochemical studies revealing up to 87% corrosion inhibition efficiency.
- Improvement in mechanical properties and stability due to graphene oxide dispersion.
This research highlights the potential of graphene-based nanocomposite coatings in industrial applications to enhance the durability of mild steel structures.
