Recent approaches for designing nanomaterials-based coatings for corrosion protection

Abstract

Nanotechnology-based coatings have shown remarkable growth in recent years in many strategic industries such as automotive, aerospace, petroleum, electronics, etc. The unique characteristics that can be offered from nanotechnology are one of the main driving forces for the sharp innovation in coatings technology nowadays. Nanocoatings have recently been proposed to add functionalities to the materials to be coated such as anticorrosion self-healing, anti-icing, self-cleaning, etc. Different types of nanomaterials have been incorporated in anticorrosion coatings by adopting various approaches. The basic approach utilizes incorporation of inorganic nanomaterials with the traditional organic coatings to enhance certain functionality of the formulated nanocomposite coating. However, one of the recent trends in nanotechnology is to design nanomaterial-based coatings of multifunctionality. These include stimuli-responsive/smart coatings, self-healing coatings, organic/inorganic hybrid coatings, and electroactive coatings. This chapter highlights these emerging nanotechnologies and presents the most recent achievements in this area.
