Abstract

L'invention concerne l'utilisation d'un biopolymère modifié, l'isatine polysaccharidique greffée sur chitosane, comme inhibiteur de corrosion pour l'acier doux dans des bains de décapage à l'acide chlorhydrique à 15%. Ce biopolymère agit en tant que barrière protectrice pour réduire ou prévenir la corrosion de l'acier en milieu acide, offrant une alternative prometteuse aux inhibiteurs traditionnels avec des avantages écologiques et une haute efficacité de protection métallique.
