▎ 摘　　要

In this work, novel zinc-graphene oxide (Zn-GO) composite coatings were successfully prepared by pulse electrodeposition in choline chloride (ChCl)/urea based deep eutectic solvent (DES). The GO sheets exhibited excellent dispersion stability in ChCl : 2urea DES without stabilizing additives and were uniformly deposited in the Zn matrix. The surface morphology and textured structure of the Zn-GO composite coatings were quite different from those of pure Zn coating, owing to the effects of GO on the electrochemical deposition behavior of Zn(II). The Zn-GO composite coatings showed higher stability and better corrosion resistance than the pure Zn coating and the corrosion resistance of Zn-GO composite coatings increased with the increase of the GO concentration.
