2.1 Introduction

The corrosion of metal is a natural process as reactive metals tend to go in their most stable form [1]. The form stable form depends on the nature of the corrosive media around the metal. The metals find a huge application in the sphere of human development. The continuous corrosion of metal leads to numerous losses of material. The corrosion of metals is a significant problem worldwide and contributes to a huge economic loss [2] and disturbs the development of any country of the world, hence metal corrosion is considered a serious threat to the economy and society (in the term of deformation metal property in the structure application). The metals at the industry level are frequently in contact with corrosive media, which immediately induces the corrosion of metal. Robust preventive measures are an urgent need to protect precious metals against corrosion [3]. The corrosion inhibitor and coating of metal are the most economic and efficient approaches to enhance the protection efficiency of metal against corrosive media [4, 5]. Various classes of materials such as corrosion inhibitors and coating is reported for the prevention of corrosion [6, 7]. Biopolymers are natural green environment-benign ...
