An Electrochemical Synthesis of Reduced Graphene OxideZinc Nanocomposite Coating through Pulse-Potential Electrodeposition Technique and the Consequent Corrosion Resistance

الملخص EN

Pulse-potential coelectrodeposition of reduced graphene oxide/zinc (rGO-Zn) nanocomposite coating is directly controlled upon a steel substrate from a one-pot aqueous mixture containing [GO−/Zn2+]δ+ nanoclusters.

GO nanosheets are synthesized by modified Hummer’s approach while Zn cations are produced in the solution and deposited on GO nanosheets using anodic dissolution technique.

Eventually, nanoclusters are reduced to rGO-Zn film through an electrochemical process.

Chemical composition, surface morphology, and corrosion resistance of the thin film are characterized.

Results show that the corrosion resistance of rGO-Zn coating is approximately 10 times more than the bare steel.
