Catechin hydrate as an eco-friendly biocorrosion inhibitor for 304L stainless steel with dual-action antibacterial properties against Pseudomonas aeruginosa biofilm

Catechin hydrate (CH) was evaluated for its antimicrobial, antibiofilm and anticorrosion activities for 304L stainless steel against Pseudomonas aeruginosa by means of surface analysis, electrochemical measurements and quantum chemical calculations. Results showed that CH inhibited the P. aeruginosa biofilm formation and killed mature biofilms. Electrochemical data demonstrated that CH inhibited the corrosion induced by P. aeruginosa with an...
