Traditional waterborne polyurethane (WPU) coatings are limited in use due to its low crosslink density and poor adhesive properties. In this study, four types of toluene diisocyanate-functionalized graphene oxide (TGO-1, TGO-2, TGO-3, and TGO-4) were prepared and used as fillers for anti-corrosion coatings to improve the anticorrosion performance of WPU coatings. Their structure were characterized by XRD, FT-IR, Raman, and SEM. Electrochemical tests indicated that the WPU coating containing 0.3 wt% TGO-2 exhibited the highest |Z|0.01HZ and R t values and possessed the best anticorrosion performance. It was primarily attributed to the excellent physical barrier effect of graphene oxide which was grafted onto polypropylene, improving its dispersibility in coatings.
