The Promise of Nanomaterials in Corrosion Inhibition

Abstract

Corrosion is a natural irreversible process that affects various materials, causing structural damage or destruction and significant economic losses worldwide. Various techniques are adopted to mitigate corrosion. In this chapter, the role of nanomaterials as corrosion inhibitors is explored for a range of applications. There are various types of nanomaterials, such as metal/metal oxide nanoparticles, nanocrystal alloys, nanocoatings, and nanoallotropes of carbon. This chapter highlights the importance of using nanomaterials as corrosion inhibitors and presents research findings on the effectiveness of various types of nanomaterials as corrosion inhibitors. Also, it describes the chemical modifications of nanomaterials including functionalization, coating techniques, incorporation of nanomaterials into polymeric matrices and development of nanocomposite which optimize their anti-corrosive properties. It also demonstrates the significant potential of nanomaterials in combating corrosion and improving the durability of metal substrates.
