Advanced applications of chitosan and derivative based bioinspired, sustainable corrosion inhibitor for metal surface protection

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. Plusieurs tentatives r & eacute;centes ont & eacute;t & eacute; r & eacute;alis & eacute;es pour remplacer les mat & eacute;riaux p & eacute;trochimiques par des mat & eacute;riaux biod & eacute;gradables et & eacute;cologiques comme inhibiteurs de corrosion. De nombreux polym & egrave;res d'origine naturelle, y compris le collag & egrave;ne, l'amidon, la chitine, l'alginate et la cellulose, sont des choix int & eacute;ressants car ils pourraient diminuer la d & eacute;pendance aux produits manufactur & eacute;s et avoir un impact environnemental favorable. Le chitosane est un biopolym & egrave;re d'origine naturelle, biod & eacute;gradable et rentable. Ce polym & egrave;re unique poss & egrave;de des propri & eacute;t & eacute;s intrins & egrave;ques remarquables, des capacit & eacute;s antimicrobiennes et filmog & egrave;nes, des propri & eacute;t & eacute;s m & eacute;caniques exceptionnellement fortes et une stabilit & eacute; thermique substantielle, qui am & eacute;liorent toutes ses effets inhibiteurs efficaces.
