investigation of the effect of ginger oil on the in situ reduction of graphene oxide nanosheets in epoxy coating and enhancement its hydrophobicity and corrosion resistance on steel substrate

Black gold, which has recently attracted the attention of many researchers due to its valuable mechanical, electrical, thermal and barrier properties, is graphene and graphene oxide(go), which is introduced as a new generation material. graphene and go is a 2-dimensional (2d) sheet of tight packing sp2 carbon atoms in a honeycomb structure witch make this attributes. the barrier and mechanical properties of go can be used in corrosion protection, especially in nanocomposites and organic coatings. in this direction, one of the most important tasks is to reduce graphene oxide and remove oxygenated and hydrophilic functional groups from its structure. therefore, after studying the disadvantages and advantages of reduction methods as well as considering the cost-effectiveness and availability of green graphene oxide reduction methods were investigated. 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) and ginger oil for preparing a hydrophobic and corrosion-resistant epoxy coating on carbon steel. ft-ir, tga and raman spectroscopy analysis showed a successful solvothermal reduction of mlgo by acetonitrile/ginger oil. the long-term salt spray and eis study showed superior corrosion protection of epoxy/reduced multi-layered graphene oxide (rmlgo) nano-coating compared to epoxy/mlgo. the water contact angle test on the pure epoxy, epoxy/mlgo, and epoxy/rmlgo coatings were 66.66°, 72.18°, and 98.20 °, respectively that confirmed the hydrophobic property of the epoxy/rmlgo coating. also, tem images showed high-quality dispersion of the rmlgo prepared by in situ solvothermal reduction compared to ex-situ solvothermal reduction.
