Abstract

In this work, the CeO₂ particles were loaded on the graphene nanosheets (GNPs) by the one-step hydrothermal method. Then the CeO₂-GNPs composite was introduced into the waterborne zinc-rich epoxy (ZRE) coatings as a nanofiller. The morphology and structure of CeO₂-GNPs were characterized by XRD, Raman, SEM, TEM, XPS. And the anti-corrosion properties of the CeO₂-GNPs /ZRE coatings were investigated by EIS and polarization curves analysis. The results showed that the CeO₂ particles with an average diameter of about 140 nm were uniformly distributed on the GNPs. The cathodic protection and permeability resistance of the CeO₂-GNPs /ZRE coatings were enhanced significantly due to the excellent dispersivity of the CeO₂-GNPs. This work provides a feasible/suitable way for the preparation of the CeO₂-GNPs material and has broad application prospects in the field of metal protection.
