Corrosion involves the degradation of metals due to the oxidation and reduction processes occurring during the interaction of the metallic surfaces with the aggressive environments. These electrochemical processes result in the impairment of materials' physical and mechanical properties such as strength and ductility. Application of coatings is the most widely used method for the corrosion protection of the metallic structures. Specifically, the polymeric coatings (or reinforced polymer coatings) protect the metal substrates from external corrosive agents by acting as an effective barrier. Besides that, depending on the morphology and structure of polymers, the coatings possess the properties like thermal, chemical and mechanical stability. These properties combined with the ability to strongly adhere to metal surfaces yield durable coatings with longer service lifetime compared with other metallic and inorganic coatings. The purpose of this book is to assimilate the recent advances in the field of functional coatings systems for achieving effective corrosion protection.For more details, please visit https: //centralwestpublishing.com
