Exploring the Efficacy of Polysaccharides as Green Corrosion Inhibitors: A Comprehensive Review

Abstract

AbstractCorrosion threatens materials in diverse industries, necessitating sustainable corrosion inhibitors. Polysaccharides, abundant natural polymers, emerge as eco‐friendly corrosion inhibitors. This review explores polysaccharides' efficacy, mechanisms, and applications. It introduces the significance of corrosion and the vital role of inhibitors, positioning polysaccharides as promising green solutions. The exploration covers polysaccharide diversity, sources, and eco‐friendly attributes. Corrosion mechanisms are detailed, setting the stage for understanding inhibition strategies. Polysaccharides, with unique adsorption and film‐forming properties, are effective inhibitors, elucidated through electrochemical studies. Influential factors like pH, temperature, and concentration effects, along with practical applicability considerations, are examined. Real‐world implementations across industries underscore polysaccharides' versatility, often surpassing traditional inhibitors. Despite challenges, this review outlines their promising role, addressing concerns and proposing future directions. Polysaccharides emerge as eco‐friendly alternatives, illuminating inhibitive properties, mechanisms, and practical applications, guiding continued research for sustainable corrosion prevention.
