摘要：

Functionalized graphene oxide (FGO) were synthesized and investigated as corrosion inhibitors of carbon steel in this research. The inhibition behavior of FGO in CO2-saturated NaCl solution was studied via weight loss, surface characterizations, and electrochemical measurements. Results confirm that FGO could protect metal effectively and the inhibition efficiency showed the extreme effect as the increase of FGO concentration, reaching a maximum of 83.4% at 20 mg/L. FGO can adsorb on carbon steel via the functionalized groups and form the hydrophobic cover layer on the metal surface by the lamellar nanoparticles.
