Abstract
The susceptibility for corrosion, poor mechanical/chemical stabilities, and adhesion of polymers under corrosive environments hamper their application as anticorrosive coatings. The microporous structure of polymers provides passage for the penetration of corrosive ions at coating–metal interface, which led to their poor serviceability. To overcome these drawbacks, advanced structural modifications such as copolymers, hybrid polymers, and polymer nanocomposites have been made. Among these, polymer nanocomposites (PNs) have enormously attracted the attentions of corrosion technologists because of their significant role in providing the enhanced service life and improved physicomechanical and anticorrosive properties. Thus, this chapter briefly discusses the history of anticorrosive PN coatings (PNCs), use of various nanofillers in polymers, processing and formulation of anticorrosive PNCs, characterization techniques, and an overview on the utilization of sustainable precursors. The advantages and shortcomings of PNCs along with the definition of technical words and future prospects have also been discussed.
