Multi-layered Graphene oxide (MLGO) were modified with Talc to prepare a hydrophobic corrosion resistance agent for epoxy through three different methods. The humidity and salt spray tests after 360 and 500 h, respectively, showed the higher performance of the sample prepared by the reflux method compared to the heater-stirrer and microwave method. The results of the FT-IR showed that in the presence of Talc, some of the oxygenated functional groups on MLGO were decreased. Also, the comparison of the experimental tests of the coatings containing 1%wt of MLGO/Talc with the different ratios of MLGO and Talc showed the best results for MLGO/Talc (1:5). The impedance modulus of MLGO–Talc, MLGO and Talc epoxy coatings at the end of two months of immersion were 1.45 E+07, 1.38 E+06 and 6.72E+05 Ω cm 2 , respectively. So by the reflux method, a hydrophobic MLGO/Talc structure was obtained that was confirmed by the contact angle test.
