Application of water-soluble polymer inhibitor in metal corrosion protection: Progress and challenges

The use of corrosion inhibitors can effectively avoid the metals and alloys, but conventional organic/inorganic have certain toxic side effects environmental pollution problems (including some expensive reagents catalysts), prompting researchers to turn their attention research water-soluble polymer with green environment friendly low pollution. This paper reviews action mechanism inhibitors, status natural (chitosan-based cellulose its derivatives other carbohydrate protein inhibitors) synthetic (epoxy resin polyethylene glycol conductive inhibitors), purpose is provide reference for development eco-friendly metal coatings.
