Characterisation of a Novel Hybrid Anti-corrosive System Comprising Graphene Nano Platelets and Non- Metal-containing Anti-corrosive Pigments

Applied Graphene Materials produces a number of GNP dispersions enabling properties such as electrical/thermal conductivity mechanical properties gas permeability and barrier type to be achievedAnti-corrosive pigments have come under environmental pressure. The challenge is to develop anti-corrosive systems with performance equal to that of current anti-corrosive pigments. Prior work has demonstrated that very small additions of GNPs decreased water vapour transmission rates and extended time to initial corrosion and has been explained by the tortuous pathway created by the addition of GNPs to a host matrix. It has also been postulated that there is an anodic/cathodic process taking place in conjunction with typical active anti-corrosive pigments.This work is benchmarking GNPs against and in combination with commercially available anti-corrosive pigments via electrochemical corrosion and mechanical testing. We seek to characterise the mechanisms by which GNPs work as anti-corrosive pigments and investigate synergistic effects which will allow improvements in coatings anti-corrosive performance. Electrochemical AC impedance Spectroscopy (EIS) corrosion potential (OCP) measurements and potentiodynamic (PD) measurements has been used to probe the properties of GNP-epoxy coatings. In their simplest form values of impedance provide useful information concerning the passive barrier properties of a coating.
