In this study, a simple and effective green in situ solvothermal reduction method of multi-layered Graphene oxide (MLGO) was developed using acetonitrile (at 70 °C) for preparing a hydrophobic and corrosion-resistant epoxy coating on carbon steel. FT-IR, TGA, Raman spectroscopy and mapping EDX analysis showed a successful solvothermal reduction of MLGO by acetonitrile. The long-term salt spray and EIS study showed superior corrosion protection of reduced multi-layered Graphene oxide (RMLGO)/epoxy nano-coating compared to MLGO/epoxy. The water contact angle test on the pure epoxy, MLGO/epoxy, and RMLGO/epoxy coatings were 66.66°, 72.18°, and 91.66°, respectively that confirmed the hydrophobic property of the RMLGO/epoxy coating. Also, TEM images showed high-quality dispersion of the RMLGO prepared by in-situ solvothermal reduction compared to ex-situ solvothermal reduction.

在这项研究中，使用乙腈（70°C）开发了一种简单有效的绿色原位溶剂热还原多层氧化石墨烯（MLGO）方法，用于在碳钢上制备疏水和耐腐蚀的环氧涂层。FT-IR、TGA、拉曼光谱和映射 EDX 分析表明乙腈成功地溶剂热还原 MLGO。长期盐雾和 EIS 研究表明，与 MLGO/环氧树脂相比，还原多层氧化石墨烯 (RMLGO)/环氧树脂纳米涂层具有更好的腐蚀保护。纯环氧树脂、MLGO/环氧树脂和 RMLGO/环氧树脂涂层的水接触角测试分别为 66.66°、72.18° 和 91.66°，证实了 RMLGO/环氧树脂涂层的疏水性。还，
