Corrosion is caused by the natural tendency of steel ions to oxidize. To address this issue, employing organic coating is among the most effective strategies to reduce corrosion. This study modified graphene oxide (GO) using D-glucose (D-g) through an environmentally friendly method utilizing distilled water as a solvent. The composite’s significant barrier and adhesive capabilities make it ideal for protecting important infrastructure in industries such as marine, oil and gas, and construction. This study presents a cheap and environmentally friendly alternative to conventional coatings by increasing the durability of metallic structures and minimizing maintenance costs, addressing both industrial issues and sustainability goals. The significant weight loss of modified GO (m-GO) at 100 °C is likely due to decomposition of oxygen-containing groups. Incorporating D-g and GO particles significantly enhanced the barrier properties of the epoxy coating. A concentration of 0.25M EP exhibited minimal thermal degradation and the most negligible weight loss. The 0.7% m-GO/EP composite provided outstanding barrier properties and improved active corrosion protection for up to 120 h. Moreover, the 0.1% and 0.7% m-GO/EP coatings showed strong anticorrosion characteristics, maintaining a larger arc after 42 days, even in highly corrosive environments. The D-g/GO composite significantly improved the corrosion protection performance of the layers. Morphological observations revealed that uncoated steel experienced the most corrosion, as water could penetrate the uncoated surface easily. The pure EP coating also demonstrated the highest anticorrosion performance and a smooth surface. This research highlights the superior anticorrosive properties of the GO/EP composite for protective coatings. © The Author(s) under exclusive licence to Iranian Society of Environmentalists (IRSEN) and Science and Research Branch, Islamic Azad University 2025.
