#### **Abstract**

Nanoclays have evoked a great deal of attention lately for the preparation of novel nanocomposite materials for several applications. This is attributed to their lamellar structures, which are distinguished by having high in-plane strength and stiffness, as well as a high aspect ratio. Nanocomposites have exhibited an advanced gas and water barrier properties compared to the pristine polymers. Such advancement plays a major role in enhancing the coating industry, specifically for corrosion protection. One main factor attributing to coating failure is its inability to maintain low water and oxygen permeability thought its service life. The penetration of these elements through the coating leads to corrosion initiation under the coating. The addition of clay to polymeric coatings has great potential to improve the corrosion protection performance of the coatings. This chapter will present the recent advancement in the preparation and utilization of clay nanocomposites as enhanced coatings for corrosion protection.
