Green nanomaterials and their anticorrosive properties

The cost of corrosion damage is very huge. Corrosion control and prevention could help to save up to $875 billion yearly on a global scale, leading to the development of green anticorrosive materials. It is also very important to develop green anticorrosive nanomaterials, to avoid toxic and polluted environments. The chapter provides a brief summary of corrosion problems on metallic surfaces, an overview of green anticorrosive nanomaterials and their sources, properties, synthesis, and mechanism. Recently, agricultural residues (biomass) have become the major source from which polymers can be obtained for several applications including anticorrosion material which can be added to anticorrosion coatings, inhibitors, and paints, because they possess functional groups containing heteroatoms that mitigates corrosion and remain nonhazardous and cost-effective. The application of green anticorrosive nanomaterials, in the form of coatings and inhibitors, environmental and economic benefits, and future trends of the green anticorrosive nanomaterials are also discussed.
