Case Study

Graphene Oxide Used for the Preparation of Epoxy-Iron Composite Coatings with Enhanced Corrosion Resistance

Sarra, R., Jalgham, R., & Nadia, Z. (2025). Journal of the Indian Chemical Society, 101765.

Graphene oxide (GO) has been employed as a functional additive in the development of epoxy/iron composite coatings to improve the corrosion resistance of steel substrates. In this study, GO/epoxy/iron (GO/EP/Fe) coatings were fabricated by dispersing graphene oxide in ethanol, integrating epoxy resin, and incorporating various amounts of pure iron powder (0.5 g, 1.5 g, and 2.5 g). The coatings were uniformly applied on X52 steel and cured at 60 °C for 24 hours.
Electrochemical evaluations including chronopotentiometry, potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS) demonstrated that the addition of 0.5 g iron significantly enhanced corrosion inhibition in 0.5 M NaCl. Microscopic analysis (SEM/EDS, OM) revealed that iron particles near the substrate/coating interface corroded preferentially, enabling both cathodic and anodic protection through electrical interactions with graphene oxide.
Density Functional Theory (DFT) and molecular simulations confirmed that graphene oxide adheres spontaneously to steel surfaces via active molecular sites, forming dense electron clouds and reducing corrosion initiation. Monte Carlo simulations also showed that increasing iron content decreased adsorption energy, supporting experimental observations of optimized performance at 0.5 g Fe.
These findings highlight that graphene oxide is a key nanomaterial for preparing corrosion-resistant epoxy composite coatings, facilitating strong substrate interaction and synergistic protection when combined with sacrificial iron particles. This approach offers a promising strategy for enhancing the durability of metal infrastructure in corrosive environments.

Graphene Oxide Used for the Preparation of Goethite-Chitosan Composite for As(III) Adsorption

Meena, Hari Mohan, Shrikant Kukreti, and P. S. Jassal. International Journal of Biological Macromolecules (2025): 145110.

Graphene oxide (GO) was used as a key component in the preparation of a composite sorbent-GO/goethite-chitosan (GO/α-Fe(OH)O-CS)-for the removal of arsenic (As III) from aqueous environments. The synthesis began by dissolving 1.5 g of GO into 250 mL of a 3% acetic acid solution under stirring for 2 hours to ensure uniform dispersion. Then, 3.5 g of chitosan (with ≥75% degree of deacetylation) was gradually added and dispersed thoroughly using ultrasonic agitation.
After achieving a homogeneous mixture, FeCl₃·6H₂O was added to the suspension until the iron concentration reached 100 mM/L. The mixture was further stirred and transferred into a 2% NaOH solution, where it was maintained for 48 hours to form composite particles with a diameter of approximately 1 mm. These particles were carefully washed with deionized water until the pH reached ~6.0, ensuring removal of residual reagents.
To improve structural integrity, the composite was immersed in a 5% glutaraldehyde-methanol solution and magnetically stirred for 6 hours, promoting cross-linking among GO, goethite, and chitosan. Following multiple washes with deionized water, the final GO/α-Fe(OH)O-CS particles were dried at 60 °C and stored for subsequent arsenic adsorption experiments.
This method highlights graphene oxide's critical role in stabilizing and structuring multifunctional composites for environmental remediation applications.

Graphene Oxide Used for the Preparation of GO-Isatin-PVP Composite for Efficient Cr(VI) Adsorption

Ghugare, Chandrakant D., et al. Chemistry of Inorganic Materials (2025): 100105.

Graphene oxide (GO) was employed in the fabrication of a novel GO-isatin-polyvinyl pyrrolidone (GIP) composite sorbent for the efficient removal of hexavalent chromium [Cr(VI)] from aqueous environments. The preparation of this multifunctional composite began by blending 0.5 g of GO with 2 g of orange peel in 100 mL of 2% acetic acid. This suspension was stirred for 24 hours, followed by heating for 30 minutes and ultrasonication for 1 hour to facilitate surface functionalization of GO with isatin moieties.
Separately, a PVP solution was prepared by dissolving polyvinyl pyrrolidone in 100 mL of deionized water, heated at 90 °C for 30 minutes. The isatin-functionalized GO and PVP solutions were then combined, heated at 60 °C, and subjected to ultrasonication for an additional hour to ensure homogenous integration. The resulting GIP composite was filtered and dried at 70 °C for 24 hours to obtain the final adsorbent material.
Characterization via FTIR, SEM-EDX, XRD, and UV-Vis confirmed the successful incorporation of isatin and PVP into the GO matrix, yielding a porous, sponge-like structure. The GIP sorbent exhibited a high Cr(VI) adsorption capacity of 119.76 mg/g and followed pseudo-second-order kinetics, indicating chemisorption. This study demonstrates the potential of graphene oxide in the preparation of eco-friendly hybrid materials for environmental remediation applications targeting toxic heavy metal pollutants.
