Publication date 2021-02-06 Keyword(s) steel corrosion seawater anti-microbial inhibitor rare-earth profilometry antimicrobial chemicals microbiologically influenced corrosion (MIC) corrosion inhibitor potentiodynamic polarization measurement Summary High strength steel in marine environments suffers from severe corrosion susceptibility and the presence of bacteria can exacerbate the effect, accelerating degradation via microbiologically influenced corrosion (MIC). Here we propose a novel approach to MIC inhibition by designing a system capable of limiting the effects of both bacteria growth and corrosion. The combination of a newly synthesised compound, cetrimonium 4-hydroxycinnamate, with lanthanum 4-hydroxycinnamate was the only system tested to date that could both inhibit abiotic corrosion in artificial seawater and minimise bacteria consortium densities over an exposure period of 24 hours. This success was proposed to be due to their compatibility in the testing environment.Furthermore, we confirmed from cytotoxicity testing that Cet-4OHCin demonstrated similarly limited toxicity towards human cells as the commercially available cetrimonium bromide, a known safe additive to cosmetic products. Thus, this new system shows promise as a safe and effective multifunctional inhibitor to reduce the effects of MIC.
