:This chapter reviews the use of smart coatings for corrosion protection. Smart coatings are coatings that respond to the environment. In general this response requires a trigger from the external environment. Triggers include the presence of moisture, pH, chloride ion concentration, mechanical damage, temperature and redox activity. Diverse methods of self-repair are outlined as are a variety of ways of holding and releasing corrosion inhibitors. Differing methods of sensing in coatings both using responsive molecules and nano-sensors are outlined. Lastly, the current and future needs for smart coatings are discussed.
