Green Corrosion Inhibitors: Natural Polymers and Amino Acids

It is profitable to use inhibitor to control metals corrosion. However, beside cost-effectiveness and inhibition performance, the modern-day corrosion inhibitor is expected to be friendly to the human life and the natural environ- ment. This chapter discusses the corrosion inhibition performances of some groups of compounds deemed to be environmentally friendly. Specifically, the natural polymers and amino acids are considered as the promising eco- friendly metals corrosion inhibitors for the future.
