Metal–organic framework (MOF)/graphene–oxide (GO) nanocomposites materials: A potential formulation for anti-corrosive coatings- a review

In modern era, metal corrosion is considered as a major issue. The development of intelligent nanomaterial with functions is crucially important for successful approaches for metal corrosion prevention in the current scenario. Graphene oxide (GO) is an oxidized derivative of graphene which contains organic functional groups, such as –OH,–COOH, and –C 2 H 4 O. The addition of these groups in some materials such as MOF enhances its potential use in anti-corrosive coatings. Metal–organic framework (MOF) is a three-dimensional hollow material with an excellent mechanical pore size distribution that is widely utilized in catalysis and adsorption areas. When GO is combined with MOFs, the spacing between the layers of the GO may be changed, affecting the transportation and screening of certain molecules. As a result, composites have a wide range of possible uses, including anticorrosion. In this paper, we outlined the present state of GO/MOF composites, including their characteristics, synthesis, and anticorrosion properties. The corrosion behavior of GO/MOF composite coatings was investigated using electrochemical impedance spectroscopy (EIS).
