Composite for self-repairing covering to hinder corrosion

Abstract Metals are widely used in numerous applications since the ancient time from infrastructure to aircraft to consumer products and hold a significant effect in everyday life. It is necessary to protect the metal especially from corrosion and has been an active research area in material science for many years. This chapter discusses self-repairing composite according to its self-repairing mechanism in three categories to hinder the corrosion as capsule-based, vascular-based, and intrinsic self-repairing material. It starts by an overview of the giant problem of corrosion and its preventive steps. It then explains how the self-repairing composite material would be a strong candidate to overcome this corrosion problem by comparing the conventional steps to hinder corrosion. By the end of the chapter the challenges facing to commercialize this technique is discussed. A full discussion of self-repairing composite material works by different examples and the relationship of its applicability with key concept is put together.
