Graphene and Graphene-Polymer Composites for Corrosion Inhibition: Structure-Property-Function Correlations, Spanning from Macroscopic to Sub-microscopic Dimensions

Corrosion mitigation of metals have great socio-economical significance. Among many strategies employed to mitigate corrosion of metals, protective coatings are widely used for this purpose. In the present work, protocol is developed for formulating graphene-polymer nanocomposite coating, to mitigate marine corrosion of copper. Mechanistic understanding of coating's durability has been drawn experimentally. Also, a sophisticated localized electrochemical technique is used to develop understanding between two-dimensional, few atoms thick graphene coating with its corrosion resistance ability. Visualization of graphene's impermeable nature against corrosion has been experimentally visualized in this work.
