▎ 摘  要

The influence of functionalised multi-layer graphene (FMLG) on anti-corrosion behaviour of zinc-rich primer (ZRP) was investigated. Electrochemical impedance spectroscopy, salt spray, cathodic delamination, pull-off adhesion tests and scanning electron microscopy analysis were evaluated. Samples were prepared using 0.25, 0.5, 0.75 and 1 wt-% of FMLG substituted by the same amount of zinc particles in epoxy containing 75 wt-% of zinc dust. Results revealed that sacrificial and barrier performances of ZRP were improved in the presence of FMLG. In addition, the adhesion and cathodic disbondment resistance showed significant improvement. The best results were obtained for ZRP containing 0.75 wt-% of FMLG.
