Abstract

It has been well documented that the inertness and impermeability of graphene/graphene oxide and hydrophobicity of carbon nanotubes (CNTs) can be used to protect surfaces from degradation due to corrosion. Direct deposition of these carbonaceous materials to protect large scale structures is however impractical due to obvious high cost and instrumentation related difficulties. One other way to use such carbonaceous additives is to incorporate them in minor quantitates into conventional metallic coatings. The sensitivity of the corrosion response of the composite coatings with minor additions of the carbonaceous materials is well established but there exists a debate about the beneficial or detrimental effect of such addition. In this report, we discuss some of the interesting observations made in our work on metal-graphene/graphene oxide/CNT composite coatings and illustrate that there exists a strong correlation between the additive volume fraction and the coating microstructure which essentially governs the corrosion response.
