▎ 摘　　要

An effective and green method including in-situ solvothermal reduction of multi-layered graphene oxide (MLGO) using a mixture of acetonitrile and sesame, ginger and cinnamon oils, was investigated for preparing a hydrophobic and corrosion-resistant epoxy coating. The efficiencies of the oils as green reducing agents with synergistic effect by acetonitrile in the solvothermal reduction of MLGO at a temperature of 70 degrees C were compared with each other. FT-IR, TGA, Raman, and Mapping-EDAX analysis showed that the solvothermal reduction process of MLGO in acetonitrile/cinnamon oil mixture was successfully performed. The results of long-term salt spray and electrochemical impedance tests showed that epoxy-RMLGO (acetonitrile/cinnamon oil) nano-coating had a significant improvement in corrosion resistance (after10 months, the impedance value was 8.1 x 10(8) omega cm(2)) compared with the other coatings. Also, the value of the water contact angle for the nano-coating was 102.80 degrees and based on Mapping-EDAX analysis, the C/O ratio was 54.45.
