Abstract
ABSTRACT Recent efforts to replace petrochemicals with biodegradable, environmentally friendly materials like collagen, starch, chitin, alginate, and cellulose as corrosion inhibitors aim to reduce reliance on manufactured products. Chitosan is a biodegradable, economically viable, and intrinsically beneficial polymer with antimicrobial, film-forming, strong mechanical, and thermal stability properties, enhancing its inhibitory effects. This study comprehensively overviews common and recent advances using chitosan and derivative-based bioinspired corrosion inhibitors on different substrates and media. Various chitosan-based inhibitors have been developed via eco-friendly and economical methods with better physical and chemical properties. This review paper deals with different chitosan-based inhibitors, their preparation methods, the behaviour of corrosion on various substrates and in different corrosive electrolytes, and their expanding applicability in multiple industries. This review also clarifies the potential areas for future research and presents some difficulties that encourage researchers to act.
