Abstract Herein, we fabricate a novel metal-phenolic supramolecular film on aluminium, which can control release of loaded biocides when S2− concentration is higher than 10 mM or in sulfate reducing bacteria (SRB) environment with a long incubation period. The protection effect of the film on microbially influenced corrosion (MIC) induced by SRB is analyzed with fluorescence microscopy and electrochemical measurement. A novel microbiological corrosion protection mechanism is proposed based on its effective roles to suppress SRB settlement and insulate corrosive medium. The intelligent film maintains a longtime antibacterial behavior owing to its S2--responsive character, which enhances the microbiological corrosion resistance.
