| Abstract | The use of epoxy (EP) coatings for the protection of steel infrastructure from corrosion is a dominant technology in modern industrial settings. Improvement of this technology by compounding with graphene materials is explored. Composite coatings are produced on steel substrates using graphite nanoplatelets (GNP), more exfoliated graphene materials (MEG), and graphene oxide (GO). The anti-corrosion (AC) performance of the coatings is evaluated by salt-fog corrosion (SFC) testing and electrochemical (EC) methods. GO is found to be an excellent candidate as an AC barrier filler in EP coatings by both SFC and EC testing, clearly outperforming the neat EP. MEG also shows potential as an AC filler by the SFC tests, but performed poorly in the EC tests, possibly due to processing issues at the concentration investigated. GNP is found to show relatively less benefit as an AC filler in EP, compared with the more exfoliated GO and MEG fillers. |
