▎ 摘  要

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 degrees 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 sol-vothermal 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 degrees, 72.18 degrees, and 91.66 degrees, 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.
